ALSO!
I went back to Microsoft consulting as a both orange and a purple badge for a number of years, and In 2011 I worked on a super secret project with Microsoft HR helping tune a badly implemented upgrade to the system tracking layoffs, so secret I had to sign a ton of docs just to know it existed. It was eye opening. In organization that size there are always layoffs, some small (like 10 people), some slightly bigger (like 100 people). They were in the height of the Skype integration (aka ripping it to pieces) and so several hundred of scandinavians/estoninans were getting an axe. I fixed the system's perf issues and got out of there asap
