I applied through an employee referral. The process took 4 weeks. I interviewed at X (San Francisco, CA) in June 2020
Interview
There was a screener interview, then 2 interviews (one behavioral and one technical). Finally, a certain amount of candidates went on to a full-day process composing of a presentation as well as 1-1s and/or panels. I didn't make it to the final portion.
Interview questions [1]
Question 1
They asked me to build a knn classifier from scratch.
The recruiter got in touch to set up a screening call. I was asked basic questions concerning my background and my motivation. Then we had a coding challenge with a question I later found on LeetCode under the Twitter section for the last 6 months.
Case study was interesting; interviewer was previously from uber so some similar interview questions, techniques do apply, overall a good engaging exercise. Nothing to complain about. Overall it is okay
