I applied in-person. The process took 3 weeks. I interviewed at Tactical Systems Network (Fort Worth, TX) in Feb 2018
Interview
They have you do one application, then call you in for an interview. Show up early and you'll get done quick. Very punctual
If you get a call back they schedule a PT test and range shoot. Be in good shape and able to shoot they hold high standards.
If you pass this you do orientation
