Glassdoor interview questions

Applied online July, 2021. A recruiter made contact about 2 weeks later, had a very pleasant call with him. The next step was to have an interview with the hiring manager, I had radio silence for the first week, that scheduled and reschedule interview multiple times. My favorite was the cancellation 10 minutes before the call. Rescheduled for next day and had a great conversation with the hiring manager, very engaging. and from that point on, I never heard from them again, I made a few attempts to follow up, but the recruiter never emailed me back. It's ok if I wasn't a match, but the minimum courtesy is to let the candidate know and give some feedback. Especially when glassdoor is all about the people and the mission to make job finding a pleasant experience.
