A recent Tweet that went viral from a young job seeker in the U.K. is reviving the debate around the use of so-called "stress interviews" that seek to destabilize candidates by making them feel uncomfortable. Managers use the technique, such as asking impossible or bizarre questions, to see if the job seeker is able to handle pressure and unknown situations. A report in the BBC says that experts are divided as to their effectiveness; some say it can sometimes backfire with the employer losing an otherwise strong candidate.
