Neutral ExperienceNo Offer

Process

I applied through a recruiter. The process took two months.

It was an easy but long process consisting of nine rounds:

Two take-home assignments that were not bad.
One full-day on-site consisting of two one-hour-long assignments with a review and code walkthrough with a senior, plus two system design interviews.
One VP round.
One HM round.
Two team meetings and matching.

Questions

There was a latency improvement and one 1-hour data cleaning and analysis.

Was this helpful?
