At first it was a short 20min recruiter call. Then they set me up for a technical phone screen with an engineer. The problem was a typical data structure / algo question, something you'd expect. I asked some cool questions and got to know more about the company. Then I was moved to the onsite, which was 5 hours. Honestly, it was one of the best onsites I've had. The questions asked were creative & really relevant to the product, and they were actually interesting to solve. They weren't too challenging, and definitely weren't like those typical 'reverse a linked list' cliché interview questions. They also asked some ML and system design questions, it was quite enjoyable - I felt like I was working through the problem with the engineer (interviewer). It was definitely collaborative (instead of 'interrogative'), which was awesome.

Variety of coding qs, behavioral, and system design interviews, online assessment and karat interview at beginning, recruiter calls through out (helpful for prep), can avoid long consecutive hours of interviews, spread out
