Scotiabank Communications Assistant Manager interview questions

The interview process was super quick. Over the course of 3 weeks total I had five rounds of interviews, one of which was in person, and had to do a writing assignment which took me a few days. They loved my writing assignment and I got rave reviews for all my interviews. After my last in person interview, I was ghosted… I had to chase them for an answer and was finally told I was rejected with a very heartless, generic email. Super unprofessional ending and very hurtful. Also why take someone through 5 rounds and an assignment to say no? You should know by round 3.
