Microsoft Software Development Engineer interview questions

I applied for the SDE intern for Summer 2019 in last August and one person came to my campus to interview in November. It's a 30-min, pure tech one. My interviewer has a really weird accent (most like from India), and could not even explain the question clearly. I was writing down my solution on the whiteboard but he just kept breaking me in the middle. As a result I could not give a complete answer until I ran out of time.

A recruiter had emailed me about the details for an upcoming hiring event. I was asked to submit my resume for an application and then complete an online assessment consisting of 3 questions (LC mediums) within 1 hour. The recruiter got back to me within a week and told me that I will be moving forward onsite to their hiring event in the following month. The hiring event consisted of four 45-min rounds with four different interviewers and 15 min breaks in between (no lunch). Primarily had LC medium difficulty questions with some OO design sprinkled in (no system design rounds). After the event, I was contacted that I got an offer within a few days of the event. Hiring events are different from the traditional interview loop. As long as you pass their bar, you should be extended an offer irrespective of the performances of others.
