Management focused on bringing in new business & protecting their practice's bottom line. Leads to not sharing knowledge & resources with other practices in the same office; and keeping team members fully&over utiliized even if it means over-servicing (anything to keep the client happy in a recession).
Also, many times teams are top heavy with SVPs and there aren't enough junior staffers to do the bulk of the work. So junior staffers end up doing a lot of work well below their level. There is a serious lack of opportunities for jr. level staff to take the lead or serve as point person on projects or accounts. And the lack of interns (except for the most profitable practices) means a lack of ways for jr. staff to develop supervisory skills. Plus, with not enough hours in the day, there isn't really time for the senior staff to mentor.
Very political environment where the deemed "up and comers" are favored heavily for advancement. (You hear the same names again and again.)
