Uber Software Engineer/Developer interview questions

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 5 different public APIs I could use and asked me to build a web app using one of them. I choose 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 4 interviews in total, 3 of them technical and the last one was more of a fit interview. Everyone was very nice and sounded very excited about Uber and it's future. The technical interviews where 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 on what Uber is doing.

I was referred by a friend. phone screen, It took about 30 minutes. It was not hard but not easy.Prepare a project that you think is perfect and present it to them. Don't be too nervous. You will be fine...............................................................
