Depends on the agency. A big one like Robert Half well there's alot of stress to produce.
An independent successful firm with a great owner that would be ideal. They truly care about you.
You have to really feel this recruiter and the firm she works for out.
I do think your finance/accounting career would be over if you changed careers after 2 years.
One thing that I've seen a few times is a recruiter leaving agency recruiting and going to work in a large company doing internal recruiting.
There can be money in it. Good luck.
