Long interview process.

First technical interview was weird because the interviewer barely spoke, and it was just so awkward. I did poorly because of that, but they gave me another chance, which I did well in. That interviewer was much better at orchestrating and communicating during the interview.

I recommend splitting your final interviews to at least two days and/or getting plenty of sleep.

Two behavioral interviews; they were fine.

Around four technical interviews, with maybe three medium difficulty and one hard.

Some interviewers in those were also kind of awkward and weren't as good at orchestrating the interview.

LeetCode hard question. Not too hard.
