Pros
Can not think of a single one.
Cons
Brutal to people. Could care less about the employees, really. "Values" are not worth the paper. Kill you with 80-100 hour weeks, then drag you in off vacation for URGENT things that are not even used. Talk is great when recruiting, then the job you end up with is not what was promised, below what you are capable of, with a supervisor who's less experienced than you are. Nothing in the firm is well funded, so it's a brutal game to get what you need to get your basic business done. Meanwhile your career counselor just points you at the stock price. Boys club extra-ordinaire and they don't even bother to hide it. If you are not on the A-list you are a perpetual outsider until you get tired and leave, at which point they sic external counsel on the basis of non-compete only to harrass you and your future employer.
