I applied in-person. The process took 1 day. I interviewed at Rayburn Electric (Rockwall, TX) in Aug 2021
Interview
Rigorous and well thought out process. Very deep questions with exercise in topology. Good questions on types of services and how they are applied. They want the interviewee to go as deep as they can to answer the questions.
Interview questions [1]
Question 1
Exercise question was about multiple locations with connectivity, where and how to place services and firewalls and porting.
