I got the interview through a recruiter, it seems like that is how they go about looking for candidates. My recruiter gave me 3 assessments, Microsoft Word, windows 7, and call center in which I passed all of them. Within a few hours he scheduled me for a phone screen with the company. The screen went well, just be very familiar with your resume and get ready to explain your working history to the interviewer.

Basic trouble shooting questions. They want to know how to think and problem solve. Don't worry about getting to hung up on the technical details. Had a 5 person panel interview.
