Uber Data Scientist interview questions

a phone call from recruiter. Then, a phone call from hiring manager and a take-home assignment. The recruiter forgot to send me the assignment on the pre-scheduled day. Then, i changed my schedule to work on the take-home assignment (I have full-time job). After I sent the assignment to them, there is no feedback. Then, 20 days later i sent an email to ask for assignment result, and recruiter said the role was filled. Very disappointed.

get a data challenge after I applied online. And I got an live interview couple weeks after I finished the challenge. It's a talk and code interview. They ask technical questions and asked you to write code as they requested. They said there will be second interview if you pass. Never heard from them again
