Trained in money-laundering
Anyone who's ever worked at a financial company will be over-familiar with the obligatory Money Laundering Training. I think I've done it seven times. Despite the promise it appears to hold out, I've yet to be approached by a dodgy geezer with money to clean. In fact none of the jobs involved any contact with members of the public or their money.
My favourite question was one which asked "In which year did the Money Laundering Regulations become law?" Fortunately, another question made an unguarded reference to "Money Laundering Regulations 2007", so I was able to ace that one, though I still can't see how knowing the year would help me as a crime-fighter.
Investment banks appear to have whole departments dedicated to devising and enforcing training on a six-monthly basis*. Experience suggests that the best strategy is to go through the training module really fast so that the answers are still in short/medium term memory when you do the quiz. Thereafter everything is forgotten.
* Oddly, there never seem to be any courses entitled How to Avoid Buying a Load of Worthless Investments and Causing the Bank to Go Bust.
