We've helped several engineers get the job at Uber

Interview Cake teaches a framework for approaching programming interviews at Uber and other top tech companies. It can be easy to think that interviewing at Uber is all about memorizing all these crazy algorithm questions, but that's actually not the case. We can teach an approach to the software engineer interview that will prepare you for any interview at Uber.

Uber interviews are known to be among the toughest in the industry. Uber's engineering team supports the growth of one of the industry's biggest unicorn companies, with some of the craziest hypergrowth that anybody has ever seen. To support their pace of growth, Uber screens their engineering candidates very thoroughly.

What people are saying about Uber's interview

Here are some positive snippets from interview reviews from Glassdoor:

  • "The interview was well planned and I felt that the interview questions were balanced and evaluated my coding, design and personality skills equally."
  • "The recruiter was also extremely helpful prior and after the interview. I think the best experience I had was actually with the recruiter. The recruiter was supportive and was kind enough to spend time with me on the phone before the interview to explain what each interviewer might ask and which interviews will be purely coding/technical and which ones will be more toward system design. This is really helpful when you go for a 5+ hours interview :). The recruiter was also very open about the Uber situation which was all over the news when I interviewed and spoke about the challenges Uber is having and how they are trying to improve on many processes."
And here are some negative snippets from interview reviews from Glassdoor:
  • "Very unique experience, heard of Uber rescinding offer, but never experienced or seen anyone experiencing it. Somehow, I really experienced it...just from my experience with them, I think my uber hr's behavior is unethical."
  • "A recruiter reached out to me on LinkedIn and after a quick phone screen (he was a contract-based sourcer), passed me to his actual recruiter. She had a quick phone call with me and prefaced the rest of the hiring process with "Well, we approach compensation by weighting it heavily on our stock" - which, in hindsight, was a huge red flag. She said she would send me a test assignment to complete before I would be able to talk to the hiring manager/team, and then forgot to send it to me."
