I applied through an employee referral. The process took 2 months. I interviewed at RTX in Apr 2019
Interview
20 minute interviews with two different Managers on the phone after my application was accepted. About a month after my interview I got a call offering me the position. After accepting there were several more calls instructing me on further steps such as drug testing, background check, and placement.
One phone call that lasted 30 minutes. Went over basic information on myself and the company. Didn't dive very deep. Heard back within a few weeks after with an offer.
