It was a standard screening phone interview with the HR department, asking the standard questions about myself and my experiences. I got ghosted, and have not heard back after the screening interview.

Unprofessional on Toronto Hydro's end and you can expect being ghosted throughout the entire process despite putting in effort to them. 3 rounds, the first is a basic phone screening that asks simple questions (e.g. Salary expectations, have you used Tableau, etc). The second was a 30 minute interview that involves you preparing a slideshow presentation for two engineers on how electricity is distributed in Ontario. The final round involved the heads of the new graduate program and was all behavioural questions. Overall, a large waste of time and wouldn't recommend going with a company that wastes your time and energy as large as this one.
