I applied online. The process took 2+ months. I interviewed at Rochester Gas and Electric (Rochester, NY) in Sept 2017
Interview
I applied online via AvanGrid's website (as AvanGrid bought RGE recently). I was asked to conduct a phone screen with HR roughly 7 weeks later. Then they asked me to perform PSP (aptitude) testing followed by a phone screen with the hiring manager and their boss. Shortly after that (less than 2 weeks) they asked me for an on-site visit. During the on-site visit they interviewed me and had me take another test. After the on-site visit I received an offer within one week. Ended up declining as I had accepted another offer in the interim.

They'll ask a myriad of technical questions relating to 3 phase AC power. Questions about surge impedance loading, relay numbers and meaning, power system equations (P=IE), etc.
