CGI Project Manager interview questions

Contacted by a recruiter about the position and decided a phone interview would be set up by a coordinator. (Great!) The coordinator sent an email the next day with a set interview date/time. No discussion about agreeable options. It was changed and confirmed by email. Early in the morning on the day of the interview, the coordinator updated the calendar invite with the word "Cancelled" added to the front and no other changes. I had to reach out to find out what happened. The cancellation was confirmed by email with no acknowledgement of how poorly it was handled.
