First you take a simple computer test to make sure you can use windows, if you own a computer you should pass no problem.
Second they give you a written test to see your technical skills, It asked alot of computer programming and technical questions. I didn't even pass and no one else in my group did either, but we all got the job so I guess it doesn't even matter.
Third they take you into a room and one of the supervisors interviews you.
They ask customer service oriented questions, with obvious answers. As long as you tell them what they want to hear you wil get the job they are not fussy.
