I applied through university. The process took 1 day. I interviewed at Hydro One Telecom (Waterloo, ON) in June 2014
Interview
It was a panel interview over the phone. Three senior engineers from my team interviewed me. They asked me a set of standard behavioral questions and also a set of technical questions. The technical questions were fairly application based and I found it a bit challenging. The behavioral questions went very well. As long as you show interests, enthusiasm, and work well with others, they will very likely hire you
