I applied through an employee referral. The process took 3 months. I interviewed at ATC (Pewaukee, WI) in Feb 2022
Interview
There's a screening interview with a recruiter followed by a panel interview with 3-4 people. The process is slow but usually just one round. For senior positions may require a personality test.
