The interview process

Described in candidates’ own words.

Reached out by the recruiter. All recruiters and interviewers were really nice and kind. OA with 4 questions, LC Medium. Then, there are 4 interviews: Coding 2 LC Mediums (45 min) + PhD Behavioral (45 min) + ML System design (45 min) + AI Assisted Coding (1 hr). Overall, the process is lengthy, but make sure you rigorously prepare and practice. Lack of practice might make you mess things up, especially in ML design and Coding rounds.Candidate-reported process
Rec screen + Coding screen + 2 coding rounds + 1 ML system design + behavioral. Coding was mostly from leetcode meta tagged top 100 - 2 problems in each interview, and the system design round went in depth.Candidate-reported process
