Going on previous years, not a SINGLE one of the candidates will have a clue what Amstrad's business entails. Therefore, Alan should hire the FIRST person to say "I should be your apprentice because I actually took the trouble to find out what your company does".
Having said that, the ability to win 'tasks' which have no bearing on the day-to-day job being offered will undoubtedly be a great bonus for any job applicant, so maybe Alan is shrewder than ANYONE gives him credit for. After all, he's clearly not earning money from his looks OR his manners.
Conclusion = pay them in American dollars. You'll get twice as much for your money.
Warning = do NOT try this in Budgens. They're wise to it and won't accept foreign currency any more.
