I applied online. The process took 8 weeks. I interviewed at Crown Castle (Canonsburg, PA) in Jan 2018
Interview
They are moving to an interview process where you get a case study. The case study usually has about 4 or 5 pages of info to review. You get about 4 to 5 days to review/prepare. Then you meet with a panel or group. They assess your interpretation of the questions and then you give your answers.
