Pros
The projects are interesting, and there are a lot of smart people who work there. Upper management tries to make sure people are able to keep track of what their colleagues in other centers/cities are doing.
Kontras
I was hired at a low position at a below market salary, with the understanding that I would be formally trained in project management, promoted quickly, and transferred. None of those things happened. Billable time is everything and everybody is fighting over billable work. People are rewarded for doing a lot of overtime and there is no incentive to delegate work to colleagues. If you are junior and do not have your own clients, you are screwed. There is no incentive for training new employees. There is no formal mechanism for training new employees. Professional development is not rewarded in any meaningful way, and some people aren't even allowed to go to professional meetings. See focus on billable time. There is no clear path for advancement. Promotions are rare. I am not the only one. Turnover in the one year I was there was ridiculous.
