The process took 1 day. I interviewed at Citi (New York, NY) in Jan 2007
Interview
Very simple and straightforward. You need to be personable because you'll be answering phone calls for your boss. Chances are that you'll be cold-calling (depends on the broker) so you might have to pitch a stock or an object. I was asked to pitch a stock. Other then that, it was all personality-based.
