I applied online. The process took 5 weeks. I interviewed at X (Singapore) in Feb 2019
Interview
Contacted by the recruiter 3 weeks after I applied. Scheduled a phone interview.
Second round was onsite with 2 scientists and a manager. 3 rounds of 45 minutes each back to back.
No response got ghosted by the recruiter after I sent her an email every week for 3 weeks
Interview questions [1]
Question 1
Leetcode hard, some sql questions and some probability questions
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
