Stack ranking is the law of the land & work-life balance is officially out the window, per TK's statements around employee comp at today's all-hands. To wit, "if you don't want to take that call after 6pm or you don't want to [regularly work thru the night to] help a team in India or Europe," you can expect to be managed out. If you're not particularly interested in climbing the corporate ladder (like, you like being an individual contributor & don't want to be a manager), you can expect to be managed out. Get promoted or get screwed.
TK repeatedly calling for "commitment" & "accountability" sounds rather hollow when you understand you'll be pitted against your teammates in CSG's corporate Hunger Games throughout the year.
