Avantages
There are some smart colleagues to work with that will go on to do great things. Some interesting projects. If you love constantly working on quantitative theoretical thinking but no responsibility actual outcomes, and don't mind being constantly on the chopping block and cut when you need a break or the economy turns, then this can be the place for you. If not, plan to learn what you need as quickly as possible and move on.
Inconvénients
You and your overworked colleagues will share in your extremely low morale, which gets worse after lackluster bonus because the company doesn't have a sustainable business model and you have to work 50+ hours a week just to keep them afloat and pay management overhead. Then there's the management who are great spreadsheet jockeys and how to model, but know nothing about how to actually invest, own, or run real estate that believe they do because they never have or will. And these are the people and egos you have to suck up to to become a favorite.
