GLG Office Manager interview questions

Talent Acquisition contacted me after my application. Had first interview over the phone. He promised to get back to me within the following week which never happened. It's totally fine not moving on to next step but what turns me down is ignorance.

Had an in-person interview that lasted over 1.5 hours, and was scheduled for 3 follow-up 30 min video interviews, to be held back to back. One of the two interviewers at the in-person was a no show. The interviewer was unable to answer benefits questions, and although she promised to have HR email details, they never did. The third video interviewer was also a no-show, wasting my time. An HR assistant promised to get back with me for an update the following week, which did not happen. When I sent an email requesting a status update on my application, I received a form letter stating I was no longer in consideration for the position, although I received positive feedback from all interviewers. Overall it seemed that the company was very disorganized, and I now tend to believe the accuracy of the poor reviews from current and former employees on Glassdoor.
