The process took 1 day. I interviewed at CIBC (Toronto, ON) in Jan 2010
Interview
It was pretty formal, but the interviewer asked very predictable questions that weren't too difficult about the markets. It was clear that they had a lot of applicants, and I found the interview to be a bit rushed - I clearly was confined to a 25-minute slot at 10AM, so I had to really spout out my information. The interviewer even had to stop me at sveral points so we could continue with other questions.
