I applied online. The process took 4 weeks. I interviewed at Southern California Edison (Pomona, CA) in May 2013
Interview
There was only an in-person interview, where they asked about cyber-security, the role of NERC, WECC, whether I had experience reading one line diagrams, draw a one line diagram of the power system including the main components such as transformers, circuit breakers, buses, power source, etc.
Interview questions [1]
Question 1
If there was a cyber-attack that completely disrupted the power system, what component(s) do you think that the hackers would try to control or disable?
