Mobile Developer Interview Experience - San Francisco, California

August 1, 2019
Positive ExperienceNo Offer

Process

  1. Take-home project. Implement it as if it were a production app. I took two days to fully implement it with all the bells and whistles, test code, architecture, etc., a fully-fledged app would have.

  2. If that passes a phone screen about various aspects of your code.

  3. If that passes an on-site where you: a) Add a feature to your code b) Whiteboard architecture questions c) Behavioral interview d) Hands-on debugging e) Manager lunch

When I was asked to do (a), I quickly realized there was not enough time to do it "correctly" in 45 minutes. So, I sort of hacked it in, with the interviewer's full OK. Something didn't work at the end, and the debugger was giving me problems trying to examine why. I clearly demonstrated I was quite capable of solving the problem, and it seemed the interviewer thought so, but we ran out of time. When I was rejected for the job the next day, the recruiter said it was because I failed this test. I don't think this was the real reason, but it left them an "out."

Until this bogus reason for not getting an offer, I thought they were one of the few companies that knew how to interview seasoned software engineers, versus most companies that want you to whiteboard what I feel are stupid problems totally irrelevant to what your job would be.
