Interview Cake Testimonials

I always thought I'd come back to you asking for my money back. But I just got offers from Google, Facebook and LinkedIn. Keep the money, you earned it.

Henrik (got the job at Google)

I landed my dream job at a certain large company! Some of the questions during my interviews were similar, if not the same, as the ones I studied on your site, so that was a huge leg up. Thanks for this awesome tool. I was hesitant to pay for it when there are so many free interviewing resources online, but the curated questions and detailed explanations were absolutely worth it.

Amy (got the job at Microsoft)

I had my first on site yesterday! IT WENT AMAZING! I answered every problem they proposed with ease (sometimes I had to stop myself before blurting out the answer -- no one likes a know it all). They asked me several questions whose solutions I can directly attribute to previous concepts or situations covered on Interview Cake! So thankful.

I used a number of resources to help prep for the coding interviews but Interview Cake stood out as by far and away the most useful. I owe you a massive debt of thanks

Chris (got the job at Palantir)

I got offers from 7/8 of the companies at which I interviewed. After not going through a formal interview process in nearly a decade, your site really helped build my confidence. You're a hero, Parker ;)

Zak (got the job at Mixpanel)

Hello Parker, I just want to say how great you are :) I think you should add more and more questions to your great website :) You are so great man! and I love you a lot :) Have Great Time :)

Having tried several resources for interview prep, I can honestly say that Interview Cake provides the most structured and confidence-inducing approach. Apart from the website itself, Parker is always willing to help with external resources advice too which is invaluable.

Akshay (got the job at Amazon)

I freaking love Interview Cake. The questions are high quality and I appreciate that the explanations are not overly verbose - just enough to clarify my understanding without overloading my brain and making me forget what the core concept is (which honestly happens with some other prep materials). The UI and animations make it ridiculously engaging. I don't want to stop preparing.

I was really hoping to get my money back from you for not getting an offer from a company, but I ended up getting an offer from Google after practicing with your platform. Thanks for the help!!

Adam (got the job at Google)

Honestly, this feels like cheating. Very efficient way to spend your study time and definitely pays for itself!

Patrick (got the job at Dropbox)

I'm extremely happy to let you know that I have offers from Facebook and Microsoft, and I attribute a lot of that to the excellent preparation that I did on your site. I solved all the questions like 3 times, and many of them appeared during my interviews.

I didn't really have the discipline when it came to sitting down and grinding through practice questions on my own. Interview Cake was like having a friend to train with.

Simon (got the job at Uber)

For someone without formal training in software, this site was immensely helpful in teaching me how to approach challenging problems. Got the first job I interviewed for, off to Silicon Valley I go!

Joel (got the job at Tesla)

I just got an offer from my #1 choice after being ridiculously nervous the entire time. It was 2 hours of white boarding, and I honestly feel like I completely crushed it. Had an offer sent to me 5 hours later. It was honestly the best feeling ever and I will be making way more money than I thought I would be at this point. Just wanted to send a huge thanks for this site.

Interview Cake was really helpful in its approach to explaining the problems and providing hints one at a time, even given my existing background in algorithms/data structures and whiteboard-style interviews. I think it's safe to say that buying access to the site was a great purchase that I'd recommend to anyone.

I got two simultaneous competitive offers from some of the big homegrown shops in ATX and in both interviews, variations of questions from your sets showed up in the face-to-face round. Well done, keep up the great research!

Your problems were great practice and were definitely the sort of problems that I saw in my interviews. Thanks!

Chris (got the job at Apple)

Your design and framework for solving problems is the best I've ever seen, thank you so much!

It feels very surreal that I did well on a Google interview given that my college professors told me I would have a hard time succeeding. In all honesty, your website taught me more about algorithms (and in a way that I retained the information) than any boring college class. Thank you *so much* for making Computer Science fun again :-)

Rabeea (got the job at Google, Snapchat and Microsoft)

When I told my friends I ran about 30 practice questions before getting the job, they couldn't believe it. They said they didn't feel prepared after practicing 200-500 questions. I told them I spent more time on each question, solving it in different ways, reading over each hint, because Interview Cake provided a problem-solving *experience* that emphasized quality over quantity. I will probably finish up the rest of the questions before my purchase expires, because — never thought I'd say this — I've actually come to enjoy practicing these questions.

Ivy (got the job at Dote)

The information and layout of Interview Cake has been phenomenal. I have also been going through the book "Cracking the Coding Interview" and it's also been beneficial, but the solutions can be a bit curt, especially if you start down the wrong path. Interview Cake does a great job at encompassing the potential solutions someone might come up with, and gently indicating if there's a better option.

I just want to let you know that your site was super useful in helping me to wrap my head around the types of questions that you see in interviews. I really like the way you focused on identifying themes that apply to a broad range of questions, and cautioned against just memorizing how to answer the most common ones. It got to the point for me where getting a significant plan for any whiteboard question was just a matter of flipping through the common algorithmic patterns and data structures in my head until I found one that matched.

Interview Cake got me thinking about problem solving in a way that helped me get 'in the zone' where I was comfortable brainstorming and collaborating with my interviewer. I would definitely recommend your site to anyone who needs help.

Riduan (got the job at Amazon)

As a completely blind computer programmer who lives in Iran, learning algorithms and data structures has always been a big issue for me. However, apart from Parker's great way of explaining things, what I love about Interview Cake is the fact that they went into a great deal of trouble to make their content accessible to me. Thanks to them, I got a job in Amsterdam, and I'm going to immigrate there in the next few days.

Can't tell you how Interview Cake has increased my confidence in facing interviews, the javascript questions have been very helpful.

Anonymous

I'm a self-taught developer and this is the first learning tool I've used that actually explains programming fundamentals in a way that I can understand without needing a lot of background. I just accepted an offer at a firm in San Francisco and think Interview Cake was a big part of that. What's amazing is that I only covered 14 or so of the available 50 something questions and that (plus my solid background) was enough to give me confidence in the interviews.

Got an amazing job. Interview Cake saved and changed my life. This is the best website if you are short on time and want to actually improve your problem solving skills instead of getting buried in an ocean of coding questions. Each of these questions teaches you so much and is absolutely enjoyable to read again and again. The best investment I've ever made.

To make a long story short, thanks to Interview Cake I got 5 on site interviews. Of those 5, 4 turned into offers. I ended up landing a job at my dream company with a massive pay increase! Never could have done it without you!

I'm aware of other useful resources such as Hackerrank, Codewars, etc. but Interview Cake is far and away the most comprehensive, high quality resource I've found for preparing for interviews.

I especially loved the explanations, which I found lacking on other sites. By making the thinking clear for each problem, Interview Cake gave me the skills to break down new problems I hadn't seen before.

Thanks to your site, I have offers from Apple, Facebook and Google. That's a hell of an ROI! I didn't go to school for computer science, and now I have multiple senior engineering offers from the world's best tech companies.

Rich (got the job at Apple, Facebook and Google)

Just go through Interview Cake and get a good sleep before interviews. That's all you need to pass!

I owe a lot to your program. It explained problems as memorable stories, which made it easier to remember and apply their concepts to other questions.

Tricia (got the job at Google)

I am so glad I stumbled on your service. It is excellent! The way it walks me through problems, gives me hints, fully explains why at each step AND is language native (Python written by someone that obviously knows Python very well!) has made it the best resource I have available. All of the other books I have address issues in Java or C++ with Python being an after thought. Your approach is giving me a stronger grasp of the language features and the proper approaches to solving problems with the tools available.

I signed my Google offer letter on Sunday. Your site really helped me into the right mindset. It's all a game, and you'll win if you have confidence and the right tools. Interview Cake definitely gave me both.

Interview Cake gave me the practice necessary to ace my technical interviews. I've drawn from the problems' algorithms and focus on time/space complexity on countless occasions. It's worth every dollar and more.

When I came across Interview Cake, it just clicked. That is how I learn. None of the other resources I came across were structured as well. The way it breaks down the approach and conclusions reached and the support for multiple languages and even the way the site is built - it's all done very well. And then you add in a money back guarantee and I'm sold!

Your site was really indispensable for the Google/Amazon interview process. I've recommended your site to everyone I know that wants to become both a better programmer and a better interviewer. Great work.

Eric (got the job at Amazon)

Interviews went well thanks in large part to your course. Your course helped increase my confidence to the point that I felt comfortable turning-down subsequent interview requests from companies that didn't seem like a good fit. I ultimately accepted an offer from my first choice, at a financial tech company in Seattle where I'll be making 50% more than at my previous job.

Interview Cake was the most efficient way to prep. I used it to completely switch careers and get offers from Google, Palantir, and Facebook

Thomas (got the job at Google, Palantir and Facebook)

The few interview books I've been using are good and some of the sites like geeks4geeks are good too, but they obviously can't give much feedback and lack the more-interactive feel that your site has. Your site really fills that gap nicely. I feel like I have an expert there guiding me along.

Finally, someone doing programming interview prep right! When I am out for a job a again, I will definitely re-use Interview Cake. Awesome!

Filippos (got the job at Uber)

I'm sure you get plenty of these but another can't hurt: I was skeptical that a website could make that big a difference in an an interview process, but after reading a lot of very positive reviews (and a mention from a Google recruiter) I bought in and wound up getting a job at Google! After 11 years in the field, Interview Cake was so helpful in relearning how to apply the fundamentals to an array of simple but tricky questions; it didn't so much teach me out to code as how to think, and that's what interviews are all about!

Interview Cake gave me an extremely detailed knowledge of data structures and concepts, and helped teach me how to apply them to an array of programming problems and questions that may appear on an interview or in real life. The problems and explanations gave me an understanding of programming that I did not even receive through four years as a Computer Science major.

Interview Cake has been my lifeline! Right now I have an offer from Microsoft and I'm still in the interview process with Google and LinkedIn. Life is pretty good, and I owe so much of that to Interview Cake. Seriously, keep doing what you're doing!

Richie (got the job at Microsoft)

I always wanted to work in the North America and I had been invited to on-site interviews couple of times before. However, It was all hard for me to get an offer from them. So I was getting prepared to recent on-site interview with your material and it was really helpful. I really appreciated that. Thank you for making those great examples again.

The explanation style used by Interview Cake (the gradual reveal of edge cases and working toward the solution) made the strategies sink in really nicely and made me feel confident about facing the interviews.

Interview Cake has really good content. But what really makes it shine is the presentation format. Keep up the good work!

The interview I had was very technical - I was quizzed on different aspects of C++ and asked to find errors in C++ code, but at the end I had to solve a problem in C! The problems on Interview Cake helped me ace that problem and I got the offer! I'm starting my first C++ Software Developer position in August! Thank you for helping people like me!

I had previously been using hackerrank to prepare for interviews and stumbled upon Interview Cake while preparing for my interview last night. I have already texted the link to my other CS friends because I found it to be great. The questions are much more applicable and realistic to a question I would get in an interview and the explanation, hints, and rational are phenomenal. They offer clarity to every concept of the problem.

I've been using CTCI to study and while the questions are very applicable, there is no feedback or hints. It's also easy to get drowned in questions with that book. I like the hints and sequential "turning of screws" like I would experience in a real interview. Last but not the least, the money back guarantee is nice.

I went through some questions and could solve most of them on my own. Also i went through the notes and tips. Really precise and helpful!

Btw, your site was definitely worth the investment. A lot of the questions you had did come up during interviews, but it wasn't the questions so much as the process of breaking down problems that was most helpful. Please keep your problems focused on that always! :D

Interview Cake was a huge help for my first job search in the software engineering industry. Other coding challenge websites have plenty of material, but the binary solutions (you either have the full solution or you don't) makes it much harder to not just learn but also understand the interviewing process. The Interview Cake questions do a great job mimicking the real experience and provide a ton of information. They're super responsive to emails if you have any other follow up questions!

Interview Cake had the best computer science-y interview prep I could find, and it really helped me get a job at Google! Solving those problems, which had detailed, interesting solutions presented in a way that encouraged me to do my own thinking, really helped me get in the right mind set.

Aaron (got the job at Google)

There were 3 major things that contributed to my decision to buy a subscription at Interview Cake: 1. The money back gaurantee is a pretty big deal, especially for a broke college student 2. It is much more structured and more carefully curated than other free options out there. Sites like leetcode where overwhelming as I didn't know where to go or what to do next. 3. It is reliable and easy to use. I had a lot of technical issues on leetcode that confused and irritated me.

The full access to Interview Cake has been great. It is a really good resource for questions and being able to browse them easily on mobile and the web made working through them on the train or elsewhere when I had time very easy.

I was incredibly pleased with your framework for problems, which present good practice problems, a space to attempt a solution and execute code in multiple languages, and also a detailed explanation of the solutions with step-by-step hints (not just someone's code with a few comments thrown in) - a surprisingly difficult combination to find!

I bought Interview Cake because of the detailed solutions that build up from more naive to more optimized solutions, much like an interviewee might build up his or her own solution.

There is no way you can know what problem the interviewer will ask. And you can not practice all possible interview problems. You have to focus in a small set of problems that will teach you the way to tackle most of interview problems. Interview Cake has those problems.

Interview Cake is an awesome service. No one else (that I know of at least) does it this well.

I did the finding change problem the other week from Interview Cake and subsequently revised all my dynamic programming knowledge. Your notes were very helpful. I then had to do a programming test for an interview this weekend and a dynamic programming question came up. So Interview Cake preparation really helped me on that one!!! I don't think I would have been able to do the code test if I hadn't been working on the Interview Cake problems.

Last year, when you came out to SF to see some students at General Assembly, I was in the audience. I had no idea what O notation even meant.

Again, Thank you so much.

You have an insanely robust and helpful platform that I couldn't find anywhere else. It was so nice to finally find Interview Cake and see beautiful, clean solutions to (really hard!) recursive and DP problems expressed in 20 lines with comments and explanations of why everything works the way that it does. The detail that you guys go to in your explanations to *guide* your students to solve a problem on their own rather than just providing a solution was instrumental in building up my interview confidence. Could not have done it without you guys and just wanted to say thanks again.

I landed my dream internship with Microsoft for next summer. After I discovered Interview Cake, it was pretty much what I based my whole study process off of - and it definitely paid off. So happy I made the investment, and thank you for the great resource!

Interview Cake has lots of unique questions you don't find elsewhere, and the approach provides a fantastic tool for learning how to approach coding questions and assess your solution.

Kevin (got the job at Spark Cognition)

I only took 1 programming class in college. I really didn't have any background in data structures or algorithms. When asked to interview at Google, I didn't know where to start. Their list of interview topics was almost like a foreign language. Long story short - your course made the difference for me. Last week I signed an offer with Google!

Holly (got the job at Google)

I'll be honest, I discovered your site about 5-6 months ago and the sample questions helped me enough to land my target a few weeks after I found it. :) Now, I visit every now and then mostly for fun since the new samples are great.

Interview Cake helped me dust off the cobwebs in a simple, practical way; this resource easily tops Cracking the Coding Interview. Thanks Parker for helping me regain lost confidence & land that highly coveted job!

I like that studying for me just means "open Interview Cake and do a problem". I do that every day or two and it's that simple. I don't have to go to different sites or read some books. Just practice with the Cake.

Interview Cake is absolutely amazing. The hint feature is incredibly useful and feels a lot like real interviews.

Deepanjan

During my interview I was asked to traverse tree different ways and I solve the problems without any issues, which quite impressed the interviewers. Honestly this happens only because I spend time solving and analyzing problem in your program. I will recommend your tools to my friends and hope to see more challenging questions in your tool.

My technical interview question was very close to one that I had seen through Interview Cake which was amazing. These questions were very helpful - much more so than the 'Cracking the Coding Interview' book that I bought. Thanks!

I bought a handful of different tools to try for interview prep. Interview Cake was by far the easiest to use and most productive.

Interview Cake was instrumental in my success for interviews. I had used few other sources to prepare for technical interviews but none of them taught me the proper method of thinking and approaching a problem like Interview Cake.

The problems are fun and very relevant, and the problem breakdowns are thorough enough to be part of a textbook on interviewing. Thanks, Parker!

I did land a job in November and I must say that, while Interview Cake's questions are hard, they did get me in the headspace to handle their much simpler questions! You have the best interview prep "book" out there and I will sing it's praises from the top of the mountains!

You know what... I landed my dream job! I'm forever grateful for your support and encouragement. I wouldn't have managed this without Interview Cake. In the actual interview, I felt so calm... it gave me the courage to tackle the technical part of the interview and made me so much more prepared for the social aspect of the interview.

I did all the weekly questions and found myself getting better and better at them, the more of them I did the more I found my entire way of thinking about algorithms changing. I then applied to Googles Engineering Residency program starting in August and after 6 or so interviews got my offer today. Thanks so much for putting this site together and providing the weekly questions, so much of how well I did is due to your site and I'm going to make sure to recommend it whenever possible.

I subscribed to Interview Cake for a specific interview, and it was immensely helpful. That was the first technical interview I had ever done, so I was really nervous. Working through your problems really helped with my confidence and refreshed my memory on a lot of things that I had forgotten about since college. And I got the job! Thanks for putting together such a great site--it was worth every penny.

Scott

I bought Interview Cake mainly because 1) I like the structure it provides, 2) there are plenty of websites out there with sample interview questions, but no others I know of that walk you through the process of tackling and answering them, and 3) if it helps me in any way to land a better job or better salary, it easily pays for itself.

I started at Google as of this week! Interview Cake was the primary studying tool I used before the onsite interview and it prepared me well for what they asked.

The exercises have also really helped me not just prepare for the interview but improve my critical thinking and foundation in data structures and algorithms. For that reason alone I'll recommend Interview Cake to my peers for really helpful practice problems.

What I like about Interview Cake is they talk about process of solving the problem. Once you learn to solve problems using these patterns you can apply them to similar problems you encounter

Before Interview Cake, I probably would have failed my Google interview. After doing Interview Cake seriously, I got strong positive feedback from the hiring committee. On top of that, it's just really fun to do. Do it.

Ezekiel (got the job at Google)

I bought Interview Cake because I was impressed by how the problems were broken down. Often when I'm by myself studying, I get stuck and it is really difficult to solve the question properly without some guidance. I can always ask for hints, and also since there is no grading system, I don't feel pressured to perform properly so I can focus on learning.

Your practice problems boosted my confidence and helped me to think critically throughout the process. And I got the job! Just wanted to say thanks.

It's a coder's full interview toolkit containing everything you need to prep for the coding questions. Plenty of samples with detailed explanations, in phases that prompt to think and say "do I really need to click the hint button again or can I figure it out from here?"

I attended a pretty rigorous coding bootcamp (Grace Hopper Academy in NYC), so I felt really prepared for a new software engineering job, as far as my actual skills. But interviewing was proving difficult and scary (I'm an extravert with a background in theatre, and I usually have no trouble with the interview process while job hunting - but engineering technical interviews are so different from the typical).

I am happy to say I have several solid offers in hand, and practicing Interview Cake problems was certainly quite helpful for me. Thanks for putting together valuable material.

Pass or fail I do not want money back. My reason? I learned so much just by signing up. I never thought about all these approaches to a problem and all because of this interview, studying for it and Interview Cake. Just goes to show I still have a lot to learn. You deserve more praises and there should be more people like you.

Interview Cake has been my go to for coding interview prep. It emphasizes both fundamentals and problem solving skills while still keeping the exercises interesting. 10/10 would recommend

Kyle (got the job at Facebook)

I only used Interview Cake for about a week before my first technical interview (ever), but the interview went great. I breezed through building an "nth lucas number" generator and a sorting challenge similar to Problem #4. After an interview with the founders, I was offered a job and felt confident to negotiate my salary. I'm happy to report I start work on Monday as a junior, front-end dev for a well respected data visualization firm. Thanks!

I wouldn't have dreamed of a job like this six months ago, but these practice problems made all the difference. Highly recommended

I came across Interview Cake yesterday and was really impressed by the step by step approach of building the logic.It was very helpful! Your site is a class apart from the rest of coding question sites out there.

Interview Cake helped me so much when I needed to accelerate my learning for interviews. If you need something to use as a study guide, check it out :D

John Paul (got the job at Microsoft)

As opposed to a book--where you either have the answer or don't--Interview Cake approaches each problem step by step, teaching you the *whole* process of finding a solution. It's unique, and very well done!

Guilherme (got the job at Microsoft)

​Yes, landed first and only gig I was applying for. Your problem set and walk-through guides were informative and interesting. Thank you for creating the site.

I got rejected in 2016 for a Google summer internship, so I decided to work harder for 2017. Interview Cake helped me a lot, the two rounds of interviews went much better, and guess who has an internship now ? =P

Parker — Thanks for all your help preparing for interviews, I actually look forward to answering Interview Cake questions and really appreciate the approachable explanations and clean code. Keep it up!

Tim (got the job at Google)

Interview Cake​​ code challenges helped me get into the mindset of explaining why a solution was valid ​instead of simply implementing an answer​. It's more important to know how the ​features actually work than just cranking out the code.​​

Sebastian (got the job at Citadel)

I've found Interview Cake to be one of the best online platforms to prepare for tech interviews. I'd say that its the only platform that actually understands the nuances of interviews and how to best prepare candidates for such tests.

I accepted a position with a new company as an iOS engineering manager. Your questions were great for helping me be prepared and also feel more confident in my technical knowledge. Thank you!

I had a few question on sorting, Big O, and some brain teaser during the interview...so I was happy I got prepared for that! I'm so happy with Interview Cake that I will continue doing the problems even though I have found a job now.

I have got a job offer at Google and will start working there in 2 weeks. I really appreciate you replying to my question about a problem and the way you explained gave me a lot insights on how to approach problems and find a solution.

Anonymous (got the job at Google)

Thanks for being a great coach! For answering all my questions, teaching me how to approach a new problem, how to think well and come up with multiple solutions and importance of understanding the tradeoffs of different approaches, how to be a better engineer :) I couldn't have asked for more!

Haripriya (got the job at Microsoft)

Interview Cake teaches you how to think through algorithmic questions, which is much more important than just regurgitating code. The solution is the least important part of these types of questions! Thinking (and talking) through the problem is what matters, and that's what Interview Cake's format teaches you.

Kevin (got the job at Google)

I got offers from Amazon and Uber! I was also invited to on-site interviews with Facebook and Airbnb, but ended up declining those. Thanks for your excellent resources!

Interview Cake nails the most commonly used Data Structures and Algorithms asked in coding rounds and covers them thoroughly. Further, It's pretty cool that the interviewing format is baked into the UI.

The tips and tricks they give you are gold! I would read through them even if I solved the problem myself because they were so helpful in guiding me to the right thought process.

Gary (got the job at ThoughtSpot)

I've heard Interview Cake is better than Gayle Lachman's Cracking the Coding Interview and seeing so many people overcome their imposter syndrome through working with your product makes me feel like I could maybe get over it myself :)

Interview Cake helped make me very relaxed and comfortable in my interviews. I could concentrate on connecting with my interviewer because I knew I was strong in my algorithms

Jeff (got the job at Amazon)

I really love how all facets of the problem are shown step by step, for instance, how you can think of a brute force algorithm first, and then reduce it in time to n or logn. It has certainly been the missing key in interviewing.

Just wanted to let you know that I got the offer from Google :) Thanks and keep up the good work

Joy (got the job at Google)

Interview Cake made all the difference for me. The questions are unmatched in caliber, and the web interface simulates real coding interviews. It's very challenging and therefore totally worth it.

Mikhail (got the job at Bank of America)

I started Interview Cake a few weeks before my interview. It really gave me an edge and made me feel more confident with appropriate and challenging practice problems. Thanks!

Jake (got the job at Google)

Just wanted to say thank you for all the help. Your program was one of my most essential go-tos during my job process and helped me get a job at Oracle! Keep up the awesome work, your program is hitting all the right notes.

Whenever I have a friend ask me how I switched careers, I say that the confidence to take a technical interview came from Interview Cake.

Interview Cake solidified my basic concept of computer science. I love the way they walk through a question step by step. It's really helpful as I'm not a computer science major.

Interview Cake helped me quickly brush up on the programming questions that I hadn't worked with since college. The problems were very similar to the ones that I had to solve during my technical phone screenings. Thanks for making a great product!

Caleb (got the job at MailChimp)

My interview is on the 25th and I am practicing questions from Interview Cake website.I like the way the questions are structured and way you explain answers. It is great.

I am excited and happy to tell you that I got a job offer from Microsoft. Practicing Interview Cake questions definitely helped me crack the interview.

I'd like to thank you for this program. Interview Cake is a really awesome tool for validating and reviewing concepts. It's also very efficient in the sense that it covers a wide variety of topics with a very elegant and consistent approach.

Gustavo (got the job at Amazon)

Using Interview Cake (and a whiteboard!) helped me feel confident and comfortable during my very first technical interview. So much so that I got the job!

Zach (got the job at Vudu/Walmart E-Commerce)

Unbelievable, but your site guided me through an extensive practicing session and finally helped me to get the job I wanted. I think I would not have been able to crack the interviews without this very unique and comprehensive collection of problems and solutions.

Tilman (got the job at NVIDIA)

Score one for your guarantee! The interactive format was more engaging than books.

Trevor (got the job at Microsoft)

The studying is been going well. Your site is pretty awesome and has been super helpful. I have an offer from my first loop and have a few more in-house loops to go for other companies.

Thanks for all the support that you provide through your emails even before one upgrades his/her account. It is not just technically enlightening but even psychologically comforting too.

It's a great source on thinking process training, one-of-a-kind, and not only for the interviews but for the day-to-day stuff also. Recommended if you don't know Knuth by heart!

Interview Cake mimics an actual interview experience - the hints are gradual enough to nudge you in the correct direction so you can learn the thought process needed to succeed.

Zach (got the job at Qualtrics)

Interview Cake was a great help in preparing for my interview. The hints and detailed explanations allow you to figure problems out for yourself and learn the thought process needed for interviews. Plus, you get a refund if you don't get the job.

Philip (got the job at Google)

I bought Interview Cake because of the format: small hints that lead up to the big picture. I'm trying to shake off some rust after about 10 years of strictly management experience, and it's helping me get back in the groove without spoon-feeding me answers.

I enjoyed sharpening my skills on the questions. A great review, since it's been a few years since I learned this stuff.

Brian

I bought Interview Cake because the questions are fun and the step by step hints are a huge help. Thank you!!

The questions were really great and the way the hints were provided was very helpful. I would recommend Interview Cake to anyone who is going to face a programming interview.
