What's an SDET you may ask? It's a Software Developer in Test. I will write code to test code starting one week from Monday.
I'm sure I'll have to sign an NDA but I can spill what they told me in the interview.
Apparently this group within MS finds bugs for major releases on the 360, their last project being Lost Odyssey.
So I get to stare at the source code for some major 360 release all day for a year!
Then maybe they'll sign me up for actual development, pretty exciting anyways.
For reference here are the Microsoft internal XBOX 360 development buildings:
microsoft millenium campus - Google Maps
I will be in the second to last. The one to the left is the XNA C# devs, left of that are some 360 major release devs, and to the right is XBOX Live development.
I went on one interview for XBL and the interviewer let slide that they're working on some major upgrade for XBL that no other service has ever implemented and that it's coming this fall.
