Always tell these people that they’re despicable to their face. It’s the only way to change their toxic culture.

So he's pissing off all the great candidates who have better options.

Wow, that's terrible. If I'm not there 5 min early to perform your interview, I'll apologize. Being on-time to something like that just invites time-wasting things like kicking the previous group out of the interview room or whatever.

An interview should be a 2-way deal, I'm representing the company and trying to find a good fit for the role, and you're trying to decide whether the company is a good fit for you. If I'm late to an interview, I expect any self-respecting candidate to leave after 15 min, and I wouldn't be surprised if they left after 5. I'm the one looking to fill a role, you're just here to see if it suits you, so it's on me to give the good impression IMO.

I was a naive young lad desperately looking for internship. I was waiting for one hour for an interview and then the hiring manager is a short lady with a stern face came to get me. I thought the interview was simple and easy enough but I didn't get the job. Looking back, it was a power tripping move. However, I probably dodged a bullet because I heard from a colleague in my previous company that the company I tried to get internship in is toxic. The employees there have been working there for twenty years and stick to each other, not talking to new people. It is an old boy's club basically.

I used to work for someone who would deliberately schedule 5 or 6 people for an interview on the same day and time, then sit and talk on the phone for an hour while everyone waited. She acted shocked when people got up and left.

yeah it honestly makes sense considering that what most job interviews are measuring is the candidate's willingness to humiliate themselves for the boss
