Uber Senior Software Engineer interview questions

The screening interview process was quite challenging. The question was probably medium level leetcode question and was expected to be solved in 20 mins with a working solution. I was expected to code on online editor and run the code. After this, the interviewer then proceeded to ask about my resume and wanted to know what's the most challenging project I have worked on

First, screening call with recruiter to learn about your background. Then, a technical phone screen round with 1 coding question, for 45 minutes. The question had a trick to it, and if you did not figure out the trick, then you wouldn't make it past this round
