There can be serious negative consequences from adopting the “Good Cop/Bad Cop” approach to job interviews. Selection panels can lose respect from GenY’s when using this approach to selection interviews because they do not appreciate “intimidation” and assume that this will carry over to the job context.
A job applicant who feels the need to bag their boss at a job interview, is typically frustrated by their boss or angry at them. They let their feelings control their behavior on interview which, in turn, demonstrates a lack of personal control. This is a fatal mistake in a job interview.
