I applied in-person. The process took 1 day. I interviewed at Textron Systems (Goose Creek, SC) in Sep 2012
Interview
Hiring involved an onsite interview with four or five managers, followed by a thorough back ground check due to the involvement with military projects and equipment. Afterward, credits check and personal reference checks was included. A tour of the facility was part of the process, with a scan coded badge. The entire process lasted better than three weeks.
Interview questions [1]
Question 1
Is there any reason you will be denied military clearance?
