This was one of the more strange and impersonal interview experiences I've had. The recruiter reached out via email, and the typical recruiter screening was just done through email.

They then scheduled the next interview for me without confirming my availability, and no information was provided on what that interview round covered.

Only to discover it was a LeetCode-style interview with another engineer, which was OK, but the interviewer was quite rude and was not receptive to questions.

Overall, a negative experience, and it turned me off of wanting to work at Microsoft in the future.
