Interview 1 was with an HR person at head office. I would say I did very well, and at the end I was told that I was shortlisted for the 2nd interview which would focus on sales and customer service. I was also given a form to fill out to provide 3 references.
Interview 2 was with 2 Assistant Branch Managers, but still at head office. There were various "what would you do in this customer service situation" type questions. I found this quite gruelling.
I was told the next step would be a sort of meet and greet with management at a branch, to see how I would fit in with the culture and personalities in an actual community branch. It was vague if this was a formality before getting hired, or an actual 3rd interview.
Later I received a call from an external company that would be calling my references on behalf of Vancity. Later yet I got a call from an Assistant Branch Manager to set up a meet.
At interview 3, the ABM seemed to think I had already been hired by head office, but I was under the impression that I was in the middle of my 3rd interview. The questions were not very memorable, mostly the same as the 1st interview I think. Things seemed a bit disorganized at this point on the company's end. It was easy though so I didn't mind.
Overall I would say the interview process was definitely thorough and substantial, not shallow. I put my personal tips in the specific interview questions.
