After a few rapid-fire phone calls, your consultant will bring you in for a short review. It's all pretty business-like, and rarely seems to take more than 15 minutes.
On the first phone call, I was asked whether I would be interested in a certain type of work.
On the second, I ran through my resume, and answered a few short questions about it.
On the third call, I specified my relative willingness to take certain positions at several companies.
During the interview, I gave a short assessment of my skills and personality.
