Staff are overworked, perpetually burnt out, and we're constantly short staffed. No one stays past 2 years and there's very little reason to; the work is repetitive and exhausting. Promotions are far and few in between and based on arbitrary terms, if management likes you and you're a favorite or how long you've been there.
Management is practically non-existent and one team director in particular is a huge mansplainer (or so I hear) and no one seems to like him. Partners are extremely unhelpful, as another reviewer noted.
Morale is also pretty low at MS right now. We've recently had an exodus (and someone got fired) – all people of color – and many others are plotting their exits. Not exactly the kind of environment people want to be in.
