Completedworks interview questions

Really weird experience with the recruitment process. I received an email requesting an interview. It was on the same day, so a little rushed but I agreed. 5 minutes past the agreed time, it was cancelled, they suggested we do it on a different date. Tried to reschedule it but got completely ignored. Tried again and still, silence, no response what so ever. The weirdest HR experience but maybe I dodged a bullet here. If the HR are this unprofessional / inexperienced then I think its a huge read flag for the rest of the company. The values that the HR department have are a direct refection of the company itself. HR, please have the courage to admit to your own mistakes and stop wasting peoples time. Nobody needs that.
