It was surprisingly hard to secure an interview in the first place. Uber was the first company where I had to use an employee referral just to reach someone from HR. I did not have any problems getting an interview at any of the top 5 companies in the Bay Area.

The phone screen with a hiring manager was quick and easy. I was prepared for a difficult coding challenge but was really baffled by how simple the actual problem was.

The onsite interview process was pleasant and very friendly, not intimidating at all. The day started with a culture fit interview with a hiring manager and HR. The rest of the day was equally divided into coding and design questions. After leaving the office, I was very happy with my performance during the interview and was almost sure I got the job. However, a few days later, I received a polite but standard response from HR saying that the team decided not to extend an offer to me.

Standard coding exercises, such as those you'll find in any interview preparation book, were included, along with some math/probability follow-up questions.

Design questions were meant to test general knowledge of modern development frameworks and design principles.
