I applied online. The process took 5 weeks. I interviewed at Microsoft (Redmond, WA) in Feb 2014
Interview
One phone screen, and then onsite interview in Redmond. Phone screen was fairly basic, we just went over resume and a brainteaser. Redmond interviews were four one-on-ones. A mix of design questions, resume review, behavioral questions, coding questions, and just general chatting. Heard back the day after the onsite interview.
Three rounds of interview starting with phone screening, middle round of online interview and final round of three interviews all schedule within a couple weeks time. Interviews were Microsoft recruiters followed by employees
Interview questions [1]
Question 1
If your boss asked you to build a coffee machine in a car, how would you approach it?
Standard behavioral set of questions, walked them through past projects I've worked out and answered some case-like product question, like what is your favorite product / non technical product, etc.
Apply the summer intern programme through official website. 2 rounds of interviews in total. Give general idea of what is a good PM and talk about the latest project. Deal with a small case.
