The worst part about career ladders at Microsoft was that it put people who were great engineers but terrible, terrible managers in positions of authority, because there was only one advancement path. When I left,they were just starting to create a career ladder for individual achievers, because they had finally realized this. I don't know if it actually ever happened.

Dunno when you left, but you can go up many levels as an IC currently.
