First round was 30 minute phone interview with HR. She asked basic questions such as why MSFT, what's your favorite MSFT product, what's your career plan, tell me a product that was marketed very well. Second round was 30 minute phone interview with Senior Product Manager. He asked me to give an example of a technical product that was marketed very well, and how would I compete with it if I were a competitor. He also asked how did I evaluate whether a marketing campaign is successful. I haven't got feedback after second round.
