Its 4-stage process: screening, coding, and two system design interviews.

Screening is mostly to check if you fit the company values and if you have the required work experience for the role. I did not have any specific technical questions, but this may depend on the candidate.

Lots of questions where the STAR technique is expected to be used: how you dealt with a technical challenge, with conflict, etc. Focus on individual qualities and not teamwork effort – the interview is about you and not other people.

Coding has two problems to solve: the first harder, the second easier. The problems are typical medium-to-hard LeetCode problems, but usually with extra steps and long, detailed descriptions, which makes it harder to decompose the problem into known patterns. Expect something non-trivial, like dynamic programming for the first problem.

System design is like any other system design. They seem to put focus on overall scalability and database design, but that is just my impression based on a failed attempt. There is only 1 hour for it, but it is expected to cover a lot during that hour, so don't try to spend too much time in the requirements part or basic design choices, because that won't give them enough input from your side to give you a good grade.

The interview process is tough, but expectations are very clear. A lot can be learned, even when failed. Got very good, extensive feedback after the interview.
