I worked at L3 Technologies full-time (More than 3 years)
Standard salary, 980 schedule (Alternate Friday off), excellent place of learning.
People who sitting on top have there own fvrt people whose information blindly trusted.
I applied through an employee referral. The process took 1 day. I interviewed at L3 Technologies.
As for the interview process, there were some technical questions and some logistics. I would recommend brushing up your engineering knowledge (circuit design, bode plot etc) before coming in for an interview.
