I applied through a staffing agency. The process took 1 day. I interviewed at Zeta Global (New York, NY) in Aug 2012
Interview
Hiring was actually done by an external company (Randstad), worked there for two weeks as a temp then got hired as a regular employee for the company but I've been to interviews and the questions asked are fair questions regarding the position being solicited and not trying to overwhelm the person with difficult questions.
