Redwood City, CAPosted Mar 2025 · Candidate report, summarized by Dataford

For the Data Scientist role, I went through recruiter screening, a behavioral walkthrough, and then a tight sequence of technical rounds spanning modern ML topics and harder coding over roughly a few weeks.

Recruiter call — scheduling and logistics after applying.
Coding assessment (HackerRank-style) — normal ML concepts plus two DS-related coding questions.
Behavioral/technical walkthrough with senior manager — resume walkthrough and tougher questions including reinforcement learning and LLMs.
Technical rounds (3 back-to-back) — first round covered basic ML plus reinforcement learning, RAG, and LLM topics; second round focused on an ML system engineering scenario; third round was coding with two LeetCode problems (semi-hard and hard). Outcome: I didn’t get an offer
