You answered questions over the phone like a pre interview, waited to be contacted to come in for testing. If you passed the test you were scheduled to meet with the hiring manager.
I applied through other source. I interviewed at Sertec (Atlanta, GA) in Sept 2014
Interview
first a phone interview, then you are called in for an in person interview. You are given a test that same day for typing and listening. The process is short and they are very nice.
