Screening - availability, reason for applying big O - Leetcode medium, maybe a bit easier than that. It's one of those exercises that has multiple phases where each builds on top of your solution to the previous one. In my case, it had 4 and it was required that I complete 3. I was informed of this beforehand although in an unnecessarily misleading way imho, as I was told 70% was the minimum "grade" to pass, while each step awards you with a score of up to 25%. Manager interview - Conflict resolution, addressing bringing up process improvements as well as my way of improving others System design - Design a system where you can show a list of transactions made by a user. The problem statement was a little misleading imho because it turned out that they wanted me to design the API endpoints and not do a client HLD, which is opposite to every other mobile design interview I have ever done, and that includes Meta, as well as what's stated on resources provided by the company themselves ahead of the interview, but maybe you can give them the benefit of the doubt and pin this on me not having clarified a seemingly-already-clear point instead.

The most difficult/interesting question I got was around systems design were you have to showcase that you understand the concepts of distributed and parallel computing, distributed synchronization, MapReduce framework, etc. But since these were skills required for the position, it wasn't very unexpected.
