Microsoft Senior Software Developer Engineer interview questions

I was contacted by a recruiter. Then the recruiter set me up with a virtual interview. The interview was conducted in 4 parts. Behavioral, coding, system design and code architecture. The first three interview I did was ok. The interviewers were friendly. However the final interview which was the coding interview was horrible. For some reason the interviewer was irritated by me since I couldn’t understand the question. The question wasn’t clear enough. Anyway I tried understand she was rude. I was actually thinking maybe the color of my skin irritated her.
