It was simply completely baffling; I honestly felt like there was no idea why I had even gone there?????

I went for an interview a few weeks ago. After completing and submitting the written test, the process left the interviewee waiting for about 20 minutes.

Then, once the information technology interviewer came in, they asked some questions about the interviewee’s past experience and background;

It would have been fine not to ask, but as soon as they did, it was immediately clear that the interviewer had no understanding of the subject at all and kept deliberately making things difficult for the interviewee.

Even aside from making things difficult, they did not raise any valid questions and just kept smirking. I thought to myself, “And then?” But there was no then ...

I understand that during an interview, you may encounter a difficult interviewer to some extent, but at least they should raise valid questions or offer better suggestions.

This company does absolutely none of that ... It was completely baffling.

I can accept waiting for you, but I cannot accept being treated this way. You can choose not to hire me, but please don’t deliberately make things difficult for or ridicule interviewees, okay? This company really deserves to be blacklisted. I sincerely recommend not wasting your time going there.
