A total of 3 technical interviews - 2 with engineers from the Perception team and one with the CEO. This was followed by an hour-long discussion with the other co-founder who focuses on product. One of the smoothest and quickest loops I've had - the HR coordinating the interviews was super responsive and the interviewers were really smart & fun to talk to. Got an offer within a week of my first interview so you get a taste of how fast the company moves.

The interview process involved a simple CV task followed by a technical round. I was asked 3 questions in the technical round, they were math based questions, 2 involving probability and 1 geometry.
