I applied through a staffing agency. The process took 1 week. I interviewed at CompuCom (Washington, DC)
Interview
Brief interview, not many challenging questions. Had to wait more than 30min for the hiring manager to show up. It's mostly just a review of your resume, verifying weather or not you have A+ certification ( which they require ). They may ask a few personality based questions.
I applied through a recruiter. I interviewed at CompuCom (Cincinnati, OH) in Mar 2014
Interview
First step was a basic phone interview. More or less to verify resume and previous job history.
Second was an in person interview
Basic Technical and PC questions. What certifications do you have. A lot of general office questions and windows questions.
Third step was a drug test and background check for the client company.
