I applied online. The process took 2 weeks. I interviewed at Unisys (Salt Lake City, UT) in Jul 2012
Interview
You'll be contacted by an out-sourced recruiting firm (I believe it's located in Bluebell, PA). They'll ask you some basic tech questions. This is an initial screening. If you pass this, you'll then be referred to a local manager for an interview. The interview consists of basic Windows operation questions, networking, troubleshooting skills, etc.
Interview questions [1]
Question 1
For me it was what a help file was, which is actually a very basic question. But as I'd never worked in a remote tech support position before, I was unfamiliar with it.
