I applied online. The process took 6 weeks. I interviewed at X in Aug 2021
Interview
The process was the following: 1. HR and Manager Interview 2. Take home assignment 3. Onsite (4 interviews, 2 hard skills, 2 product-oriented ones) 4. Final interview with hiring manager
Interview questions [1]
Question 1
The only really difficult interview was the onsite. The hardest IMO was the most technical portion, which was a probability problem and a standard coding challenge. The questions were along the lines of: a standard game of chance with dice and to calculate some probabilities; and to program a function that calculated something based on a probability distribution.
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
