Microsoft Software Engineer Senior interview questions

Initial Teams video pre-screen "whiteboarding" a theoretical design followed by a 6-hour interview circuit with 4 1-hour interview sessions taking place on a single day. Each interviewer decides whether you're writing code or whiteboarding the solution (sometimes they give you the flexibility to pick which). Two were clear with requirements and I thought very helpful with their hints, while the other two did not present in a clear way. As always, if I had seen the particular leetcode questions ahead of the interview I'd have done much better (partially because I wouldn't need to rely on the interviewers to clarify reqs, etc.). They were all what I would classify as "leetcode medium" questions. I feel that doing these interviews with MSFT and AMZN and others is a decent way to prepare as I haven't really seen technical interviews that were harder than those from MSFT and AMZN, however you really have to grind for several months (after work) or a few weeks (not holding down a full time job) at least to clear enough of these potential leetcode problems to where you will have seen (ideally) all of them already when you get into the interview. That's always been my gripe with these intervews- anyone who passes them has probably completed the same basic problem on HackerRank and it's not "really" a test of coding ability so much as it's a test of memory.

Started with a 30 min phone call from hiring manager. Then first technical interview, after that home assignment that sould be delivered in 48 hours. Then second interview to go over the home assignment. Then a technical interview with team leader. And the last one was AA interview with manager from other group in Microsoft.
