Gameloft Project Manager interview questions

I applied online and was reached out to by an internal recruiter to schedule the first interview. I sent a few emails back and forth with her prior to the interview, but on the day she didn't show up to the screening call and didn't reply to my email asking if she needed to reschedule. There was no heads up about the interview being cancelled or any explanation as to why she didn't show up so I was left waiting in the zoom call for an hour before I gave up. This is very disrespectful and unprofessional, and should not be the standard that Gameloft holds themselves to.
