After applying online and talking to the recruiter on the phone, I was asked to do a coding challenge. I had as much time as I wanted. The coding challenge was very open. They gave me five different public APIs I could use and asked me to build a web app using one of them. I chose one that gave me real-time data on transit times and schedules.

After the coding challenge, I got flown into their head offices in San Francisco. I had four interviews in total; three of them technical and the last one was more of a fit interview.

Everyone was very nice and sounded very excited about Uber and its future. The technical interviews were mostly about algorithms, data structures, etc. They also asked me why I was interested in Uber; they want people that really believe in the product and in what Uber is doing.

Algorithms questions.
