Uber Software Developer interview questions

First round was a technical phone call with a software engineer. Got an easy/medium question. The interviewer was not so responsive. It's hard to communicate with them. I got rejected some days later.

Standard tech interview process. Recruiter contacted me after submitting my resume for a quick 15minute phone screen. The first technical round was live coding with an engineer. Was able to solve the problem and discuss the time and space complexity but did not hear back after the interview.
