Uber Developer interview questions

Refer by a friend and contacted by recruiter for phone interview. Arranged the interview in one week. Did not prepare much and then interview and then failed. Uber has difficult interview questions, compared to other company and they want more senior engineers. Suggest to prepare really well before apply .

Started off with a few calls with the recruiter, then got set up with a technical phone interview with one of the engineers. The question was pretty easy, any fool that knows how to code should get it. Then I was called for an on-site interview. There were a couple of easy technical questions, and a lot of them wanted to discuss a problem I solved or what I do at my current job. So in the end, I had to explain my work like 3 freaking times to 3 different people, which is probably my fault for talking about the same thing, I probably should've prepared different problems to talk about.
