Microsoft Software Engineer Internship interview questions

Applied through campus recruiting. Had first round interview on campus. It was around 30 minutes, and went through resume questions. Was asked to talk in detail about a project from my resume. Did not hear back from Microsoft for about 2 - 3 weeks, and I was suddenly contacted to schedule an on-site interview. On-site is standard 4 rounds of technical questions, data structures/algorithms. Heard back from them about 3 days after the on-site.
