I applied through an employee referral. The process took 3 months. I interviewed at UTC Aerospace Systems (Rockford, IL) in Mar 2012
Interview
Employee referral expedited the process. Applied on line (lengthy form). Then phone screen. On site interview with a range of staff: hiring manager, other engineers, manager above hiring manager and finally human resources. Lunch with hiring manager & above. Waited fairly long for approvals to get through the system. As a large company within a giant corporation, the process can be lengthy due to bureaucracy.
