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.
I just read some article about how Germany has supposedly been experiencing a decline in the club scene for some years, and how there's a word for it.

Not the article I was thinking of, but the word is clubsterben.
