Microsoft PM Intern interview questions

Left resume at school job fair, called up for an interview. Walked in the room, and interviewer was very patient and nice. Asked me questions and lasted around 25 min.

Very long process that included initial contact for an interview invitation by a recruiter, followed by a 1:1 interview at University campus, and finally 2 months later an on site interview in Redmond. Met with three different full time employees, asked general design questions, why I was interested in PM, and details about projects that I've worked on in and outside of school. Some coding/algorithm questions as well.
