Toronto Hydro Engineering Technologist interview questions

3 interviews, 1 engineering test, 2 IQ tests. pretty straight forward interview. First interview was screening and second was all behavioral questions. Also, they show you the questions before the interview and give you 15 minutes to go through them. for the last interview To be honest i am not sure what is the point of the third interview it was with senior management and they asked about 3 questions (what are some challenges you think you will face? why toronto hydro? what is your long term plan?) in my opinion these questions couldve been asked during the second interview.
