Once you apply (usually by emailing the listed recruiter your resume), the process moves pretty quickly. They can often interview you 1-2 days after your application is received (if there's a need to fill a spot). First, you'll have a brief conversation with a recruiter, then you'll have an in-person interview with the recruiter and account manager. If all goes well, you'll go on site to the company you'll be contracted for and interview with their management team.
