Pros
People might be impressed if you say you work here. But I assume if you can get a job here, you already have a recognizable school/previous job experiences on your resume. Also, the name recognition is pretty confined to circles within finance, and if you are not 100% sure on being in finance, you are probably better served going to a big bank/other institution. There are very smart people here. There is good job security, and the pay is industry standard starting out (you'll quickly get outstripped by peers the longer you stay). You won't get better WLB anywhere else.
Cons
It's probably as dead end of a job as you can get from a reputable company. There are three reasons for this: 1. There is little growth in your role. 2. There are few opportunities for lateral movements within the company. 3. You gain very few transferrable or useful skills from what you do. I think (1) and (2) are pretty common pain points for large institutions. (3) is what I would call out if you are just starting out your career, since middle management doesn't really know what they need their analysts/associates to do and for the most part aren't particularly interested in figuring it out (there are a handful of exceptions). So you will most likely be doing a lot of random things that don't add much to your development, and then they'll ship you off to b-school. In my opinion this is a result of the org being both lean (not many resources to develop you) and hierarchical (few opportunities). That's a deadly combo!
