Uber Software Developer interview questions

I was referred by a friend. After that I had a basic phone screen to see who I was. After that, I had two technical phone screens. It took about one week for them to schedule the first one and then I waited two more weeks until the second. The first was pretty easy, a basic array algorithm questions that you would find in Cracking the Coding Interview. The second phone screen was much harder. There was only one question, but was much more involved to answer.

Contacted by recruiter through LinkedIn. The interview process was standard like talking with the recruiter about background and interests, and technical phone interview. The process was smooth and promptly. The technical phone interview on string search problem which required recursion to get the correct result. I got stuck in the middle, the interviewer gave me pointer by asking different questions on my approach but couldn't finish in 45 minute time interval.
