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 required work experience for the role - I did not have any specific technical questions but this may depend on candidate. Lots of questions where STAR technique is expected to be used - how you dealt with technical challenge, with conflict etc. focus on individual qualities and not teamwork effort - interview is about you and not other people.
Coding is two problems two solve, first harder, 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 problem to known patterns. Expect something non trivial like dynamic programming for 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 failed attempt. There is only 1h for it but it is expected to cover a lot during that 1h so dont try to spend too much time in requirements part or basic design choices because that wont give them enough input from your side to give you a good grade.
The interview process is tough but expectations are very clear, lot can be learned even when failed. Got very good extensive feedback after interview.
