One of the questions I got asked in the interviews I discuss below was whether we used agile methods and how things worked. Brad, from the CodePlex team, has a great post with an introduction to their process.

One sample paragraph:

On the team, our process is very similar to eXtreme Programming (despite Microsoft's current infatuation with Scrum, we are still doing an XP-style planning game). The team has been running one week iterations for more than a year, with our PM George now leading both the iteration planning and stand-up meetings. Now that we have launched the site, we plan for frequent releases of the software (our plans right now are roughly every three weeks, to ensure that we have given each release adequate regression testing and stabilization time).
