Microsoft Software Engineer(Internship) interview questions

Came in contact through a university career fair. Chatted with employees at a booth and submitted my resume. They took notes down as we talked about my experience. A recruiter helped schedule an on campus interview with a software engineer. The interview was 30 min long. We talked for about 5-8 minutes about general material/experience. Spent about 20 minutes doing an interview question. Then I was given a couple minutes to talk about any projects I've been working on.
