Difficulty level of Uber phone screen
It all depends on the Interviewer. I ask Medium questions. You won't be doing Leetcode in your day to day, I just want to see how you attack a problem and the quality of your code.
Time waste interviewing with Uber.
Why so
Had a phone interview: Solved two problems with optimal solutions by discussing various approaches. Corrected the interviewer for his mistake regarding time complexity. Was expecting a call but unfortunately got standard rejection email. Seems like an ego problem.
