It is the penultimate week and the five remaining candidates must face their biggest verbal challenge yet, as they stand alone and face a gruelling interview process. There is no hiding place as each of them is grilled by four of Sir Alan's trusted business colleagues. It is a test of character as every aspect of their personal and professional lives is put under the microscope. Sir Alan's four advisors will report their findings to him in the boardroom, and the candidates will then jockey for a place in the final as they meet the most rigorous interviewer of all: Sir Alan Sugar.
