I applied online. I interviewed at Uber in Dec 2019
Interview
I was contacted by the recruiter from Uber, we set up the interview date. The interviewer was a data scientist who has been working there for 3 years. Everything was professional and not stressful at all, the recruiter gave many useful tips.
Suppose we use push notifications to convert Uber riders to Uber Eats users. How do we determine what kind of people get annoyed by the push notifications?
I applied through a recruiter. The process took 3 weeks. I interviewed at Uber (San Francisco, CA) in Jan 2017
Interview
Hour-long phone screen with a hacker-rank, a take-home, then a full-day onsite with white board coding, project discussion, business case and statistical concept discussion. All were fairly standard with an emphasis on applying mathematical/statistical concepts to business problems. Coding was standard except it had a probabilistic software element.

I applied through a recruiter. The process took 4 weeks. I interviewed at Uber (San Francisco, CA) in Nov 2019
Interview
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.
