Microsoft Software Engineer (internship) interview questions

phone screening with hr, 30 mins. asked different questions about projects i had worked on, why i want to work at microsoft, what interests me, problem solving question with marbles.

My University had a Microsoft rep come to campus and interview in person. He asked a basic DFS question, and I was then ghosted by the University recruiter. I pinged them 4 times over the span of several months before abruptly offered an onsite.
