No corporate culture. At all.
Very hierarchical. Administrative staff at the very bottom of the chain and indirectly, made to feel that way. Perks abound at all levels but not if you are an admin (firm conferences, new hire dinners, team building retreats...not if you are an admin). Huge dichotomy between investment teams and administrative professionals.
Very little (almost zero) training. A few sessions are offered here and there for new technologies, but don't expect any new hire training as an admin. You'll receive an administrative handbook, desk, computer and access to all the supplies you need, but there is no ramp up and no formal new hire training for administrative staff. None. As a result, people are left to sink or swim and sadly, some good people leave b/c they weren't afforded the resources or time to find their feet.
High turnover. Mostly admins seem to be fed up or find something more interesting, in light of all the benefits and pay.
Senior management doesn't seem to know anything about what the administrative staff experiences and they don't inquire about it either.
Some tenured administrative assistants have moved up the chain in to interesting roles, but that is few and far between.
Overall, if you are an admin and corporate culture is important to you, then this is not the place. I cannot speak for the investment teams that seem to bond and get together frequently at sponsored events.
