I applied through an employee referral. The process took 3 months. I interviewed at RTX
Interview
Not sure why but the Interview process moves very slowly, even when the job need is critical. Just be prepared to wait to hear each step of the way. Quality of internal HR is very inconsistent so speed of response may depend more on how much your potential boss is willing to push the system. General sense is they really do try to get a good fit and meet with or at least phone screen many people for each spot.
Interview questions [1]
Question 1
Nothing actually. Very straightforward questions as to why was I interested in the position and what relevant experience did I have.
