I don’t think that people need to go to a job interview if they don’t intend to take a job — that’s wasting their time and that of the interviewers.
But that’s not what the parent comment is talking about. He’s talking about no-shows. Someone schedules an interview and then just never shows up.
I think that it’s pretty unreasonable to just no-show a job interview if you don’t want the job. Call and cancel.
People who are interviewing are going to organize their day around interviewing you. It dicks with them to leave that block allocated.
When he’s taking about ghosting the job, he’s not saying that people should be obligated to not take another, preferable offer. He’s saying that they never tell him that they’re doing so after telling him that they’re accepting his offer. Call and at least tell them that you’re pulling out.
It’s also going to cost more, because you almost certainly are only going to be using your hardware a tiny fraction of the time.
