Eight volunteers have five days and one mission: to ace the world's maddest job interview. Some have had or are still managing significant mental health conditions, others have not had any at all, but all are putting their work skills under the microscope in order to challenge the discrimination that sees one in five workers claim they are eased out of their jobs after telling an employer about their mental health issue. Over the last two weeks these eight volunteers have already appeared across major Channel 4 programmes like Location, Location, Location and Come Dine with Me. Now they've come together to try to impress 'the employers': a top panel of business people. Claude Littner, Elaine Holt and Austin Gayer monitor their performance to determine how employable they are, but are not aware of their personal histories - and must therefore judge them solely on their results.
