Brown Brothers Harriman Internship

Wondering what people have to say about BBH these days in terms of pay, culture etc. Also if an M&A/Private equity internship there would be a good experience for junior summer/ would a move to bulge bracket or buy side be possible?

A lot of the posts on BBH talk about low pay, not dynamic, etc. but I know several partners at the firm who all do incredibly well so just trying to get a feel for the place, thanks!
