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

I cannot thank you enough. You are really doing a great job helping so many people. Thank you for your tremendous effort in putting this site together

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.

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

They just called and told me I passed! The interviewer was very impressed by my algorithms and data structures knowledge and it was all thanks to your website. I don't remember how much I paid for the Interview Cake, but it was money well spent, every cent of it.

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.

It has been my dream for a long time to work at Microsoft so I wanted to say thank you for helping make it a reality. Wanted you to know that you have made a large and positive impact on my life.

Just wanted to let you know your site was very important for both building up my confidence with interviewing anywhere and also executing at a high level during the interview process. You have a great product and I hope you keep doing it for the foreseeable future as I am sure it will help out many engineers achieve their dreams/goals!

Got an amazing job. Interview Cake saved and changed my life.

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 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

I just starting looking at some JS questions for the very first time and am in love!!! You should write a book!!! NO, write all the books!! Great job!!!

Frank

I wish I had known about this website back when I was in algorithms class in college. This made me finally understand a number of concepts that had eluded me for years.

Luna

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.

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 just wanted to say great job and thanks for putting together something amazing to help us nervous interviewees. :)

I bet you get a million of these but I wanted to send a thank you. I was at the end of my runway on a failed startup and needed to look for work, but I hadn't interviewed or had an algorithms class in over 3 years. I set up my very first interview, it wasn't even coding, but bombed it horribly. I was pretty distraught. I found this site and bought it immediately. I wouldn't even ever say I had a good process for looking at the problems. Sometimes I would do a couple in a day, sometimes I'd go a week or more without looking at any. I didn't even look at all of them. But I had built up a constant thought pattern, thinking about issues, diff solutions to diff problems, tweaking the algorithms mentally. Anyways 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.

I highly recommend the full course for new engineers and for old-time engineers like myself who want to get past the interview coding challenge.

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 :-)

I decided to switch jobs while out on paternity leave. Paid for your service five days after the birth of my son. Interviewed with Amazon twelve days after the birth. Got an offer the next week. It's an excellent service. Easy to work through and learn from even for someone with an infant.

You are awesome!!!! This stuff is amazing... You rock...

You made me excited to learn more about data structures, and for someone who hates this stuff because blindness has always prevented him from learning them, that's a huge achievement. Trust me, I was wearing a goofy grin as you walked me through all of these data structures because, for the first time in my life, I was understanding what a hash is and what the point of its existence is.

Landed my dream job today actually! Couldn't have done it without Interview Cake. (I recommend you guys to everyone!)

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.

Thanks a ton for making such a great tool, especially with the target audience of people who may not have a formal training in CS. I love seeing what people are doing to make this field more accessible to others. Keep up the great work!

I'm sitting here at Google engineer orientation during a break and reality just hit me. I'm an engineer at Google. The only reason I am an engineer at Google is because your website helped me reign in my experience and knowledge to be effective during my interview process. Your website was so helpful that I didn't just receive an offer from Google, I also received a competing offer from Amazon. Not in my wildest dreams would I have ever thought that I could make it through their rigorous interview processes! So, if you do read this, thanks. Interview Cake does work and my life has changed a lot because of it!

Michael

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

These exercises solutions and walkthroughs kick ass!

I just wanted to thank you guys for having an absolutely amazing product. I just got my DREAM offer, and I would definitely say that Interview Cake played a good part in helping me prepare for the interviews.

I got the job! Thank you to you and your team who built a product that changed my life! I'm going to Facebook!
