You don't want to pass an interview like that.

Its an effective way to sort out those candidates who are not able to leave private stuff at home.

It’s absolutely not. Putting people in a vulnerable position and then pressing them for information you don’t need and should not ask for is a good way to demonstrate that you are an unethical or at best incompetent interviewer.

It might be a good way filter for candidates that have a high tolerance for being mistreated, though, if that’s the goal.

Also a great way for candidates to filter out employers who play bizarre mind games and think personal trick questions are appropriate in an interview.

Literally he’s saying to behave inappropriately in a professional interview and see if the candidate plays along. Might as well see if you can get the candidate to offer a bribe or sexual favors for the job since we’re going all in on entrapment.
