Submitted an application, underwent multiple interview rounds via Microsoft over the course of several weeks. There was a long lag between the application and interview process, but after the first the subsequent one was fast in succession.

Interviewed online and didn't get a response until about a month later. Had a phone interview with HR and two in person interviews, including with the Executive who I would be working directly under. Everyone was really nice and this process went pretty quick but then never heard from them. When I emailed to follow up a few weeks after the last interview, they said they were still in the interview process but never gave me a definite answer after that. I expect this from bigger companies when I just have a phone interview, but when I make it to the final round of interviews, I would hope for the respect of at least an email saying I didn't get the job.
