There's a moment in Channel 4's World's Maddest Job Interview where three employers pause and consider whether they would like to give a job to someone who has repeatedly felt suicidal.

"You'd want to work with someone who has depression, something I as a layman would think of as an illness that can be controlled and managed, but something like suicide … that's so on the edge, so serious that I wouldn't really know how to cope with it at all," Claude Littner, a colleague of Lord Sugar, who has appeared as an interviewer on The Apprentice, says, before concluding firmly: "I would be sad for them and I would not employ them."
