Pros
I worked at the Shanghai office, and the starting salary for freshly grads is not bad (in terms of local standards).
Cons
You don't have too many exit paths for staying long. If your goal is to be in a BD/sales/account manager/ position down the line, this job might lead you somewhere. If you're planning to go to the client's side of the expert network field, however, i.e., funds or strategy consulting firms, this won't cut it -- what you do 80% of the time is calling people, which is just a small fraction of the clients' work. I've only been in the company for half a year and already am one of those with longer tenure. Many this is only an Asian work culture thing, but the upper management expects the employees to reply to clients' instant messages on weekends, and I've found myself having to deal with menial things outside of work hours.
