Pros
Might get roughly market salary.
Cons
The company sells snake oil (sorry, homeopathy) to the desperate and ignorant. Rampant nepotism leads to incompetent upper- and middle-management. Don't worry, they will micromanage everything. Badly. They also threaten to fire the entire team from day one. Expect to work 20 hour days, 7 days a week. Be extremely guarded with your manager -- they are constantly documenting everything and taking things out-of-context so they can rake you over the coals on your evaluation. 360 evaluations mean any incompetent, petty, or jealous coworker can totally torpedo you. I saw three managers in four months (the last being the COO taking over daily stand-ups for an engineering group). And get used to teams of more managers than engineers. It's a sycophantic race to the bottom.
