The Apprentice (UK TV series): The Apprentice is a British reality game show in which a group of aspiring businesspeople compete against each other in a series of business related challenges, in order to win a prize offered by British business magnate, Lord (Alan) Sugar.  For series one to six, the prize was to become his "apprentice" and work at his former company, Amstrad (sold to BSkyB in 2007), or one of his other companies, Viglen, Amsprop or Amshold, receiving a six-figure salary, but since the seventh series, the prize is £250,000 investment towards a business of the candidate's creation, with Sugar as a 50% owner.  Rumours of a UK version of "The Apprentice" were confirmed in early 2004 by FremantleMedia, with the BBC successfully outbidding Channel 4 to secure the rights for the show.  Billed as a "job interview from hell", the programme operates in very similar format to that of the American original, with its creator Mark Burnett producing the UK version; Lord Sugar became the finalised choice to head the programme's first series, after the broadcaster's initial choices, Philip Green, Felix Dennis and Michael O'Leary, turned down the offer to head the show, whereupon he returned for subsequent series after this, despite initial doubts he wouldn't for the second series.

Mock interview: A mock interview is an emulation of a job interview used for training purposes.  The conversational exercise usually resembles a real interview as closely as possible, for the purpose of providing experience for a candidate.  It can help a job applicant to understand what is expected in a real job interview, and can help an applicant improve his or her self-presentation.  Mock interviews can be videotaped; the candidate can view the tape afterward, and get feedback.  There are coaches who can provide feedback on aspects of the interview process.  Mock interviews are most common for job interviews, but may also be used to train public figures to handle interrogations by journalists, as well as help candidates for office prepare for debates.  Some organizations schedule mock interview events to help many students prepare for job interviews.  For example, some schools have mock interview training days, often organized by career and guidance counselors.  While the usual sense of the term is an exercise done as a form of preparation prior to applying for jobs, there is another sense of the term which describes a playful or non-serious interview.  Mock interviews can help a person gain confidence for real interviews, as well as provide the interviewee with information about how to handle an upcoming interview.
