Uber Software Engineer/Developer interview questions

The most responsive interview process I've had. I applied for the position online and the technical recruiter reached back to me the next day. She asked about my background and I was given the choice of either submitting a code project I was proud of or completing a coding challenge within a week. I opted for the coding challenge and spent an entire weekend implementing it. I was then arranged a phone-screen with a senior software engineer. The phone interview was a live coding session and we had to implement a feature on the browser together. Later that day, I heard back from the recruiter and she invited me to fly to San Francisco from Toronto for an onsite interview. The onsite interview consisted of four separate rounds of 45-minute interviews. The first three rounds each had two engineers and I was asked to write working code and design on the whiteboard. Each round tested knowledge on a specific domain: in-depth coding, architecture design, breadth of knowledge. The last round was a design discussion with an engineering manager. I heard back from the recruiter the next morning and was presented with an offer.

I was referred by an internal employee. We started from a recruiter phone screen, following by a code challenge. After the code challenge, I am scheduled to talk with Hiring Managers from two different Engineering Team and I decide to go with the Growth team. After the hiring manager screen, I am scheduled an onsite interview. The onsite interview consists of four technical session and one manager wrap up. Everyone is nice, and the questions are interesting as well.
