Pros

Great deal flow. Get to work on some interesting deals and you will learn a lot as a new analyst or graduate. Firm has some amazing senior bankers who are really good at what they do. There's room to develop if you really want to do it. But i can't speak for experienced roles / hires.

Cons

Office politics don't matter as much as an analyst but it's certainly there and you'll notice that. Work could be a lot sometimes (benched marked against investment banking standard) and middle mgmt. is pretty weak. And there's no incentives to fix that because it won't affect topline.
