Best: Teamwork, collaboration and firm or group success is encouraged, appreciated, respected and rewarded; whereas self-promotion and being "sharp elbowed" is frowned upon.

Worst: Sometimes, due to being a top tier firm with a lot of deal flow, career development just happens as a result of the need to execute and staff people on projects to get the work done rather than a more deliberate staffing effort based on any sense of individual career development. Come with the territory of being a top shop.
