Applied after being contacted by an Uber recruiter.

One-hour phone screen was actually an office visit. We discussed programming topics and I was given a CS question about sorting. I heard back after a couple of days and was invited to a six-hour marathon interview.

One interviewer asked a highly specific GIS map-data related coding question. I stated I did not have knowledge in this area, and I was not applying for a mapping position. He changed to another question about sorting.

During another coding exercise, I was asked to build a solution and follow their specifications. The Uber recruiter had stated before the interview that following specifications was very important and that not doing so was where many applicants faltered.

Post-interview feedback stated my skills were not good because I did not implement X, despite never being asked to do those things. I should not have listened to the recruiter's advice after all.

Overall, a negative experience.
