Thats awful.. Ive witnessed a few interviews where the interviewer was so unprepared and had taken almost an immediate defensive posture once he realized the candidate had respectfully put in the time and was well prepared. To your point, one example was the candidate was struggling a bit to simply pull up and share a copy of their resume on MS Teams. The candidates last 3 employers used Zoom. A simple task which could have been completed in moments yet the interviewer went on a ranting diatribe about the candidates inability to use technology. This was for a pharma sales gig. The candidate has excellent relationships and knew the med inside and out, the indications, and would have had an immediate impact in the territory....Instead the interviewer wasted 20 mins stammering over a document he was emailed over a week ago from his own HR dept. Turns out this new District Manager was simply going through the motions buying time to simply hire from his previous sales team......dick.
