I applied online. The process took 4 months. I interviewed at RTX (Andover, MA) in Nov 2012
Interview
It takes a very long time as they have to go through a the proper channels since they are a defense contractor. The process involves interviewing with at least 4 people who give feed back to avoid any bias by the hiring manager. This is all done in one day and can take several hours as a lot of the staff have meetings and other priories they need to attended to.

Question 1
All the questions were the standard interview questions about my experience, about me personally, and about what I wanted for my future.
