An investment banker is looking to hire a new secretary, and has narrowed down his options to three women. While most people in his position would want her to sit and look pretty, he wanted someone dependable. He wanted someone who could offer him good advice when he needed it, and might even reach a position like him in the future.

To this end, he offered each woman a test. He gave each one £10,000 and told them to invest it. After a month, they would return the money to him, and this would serve as an interview.

The first woman invested in hot new stocks, hoping one of them would pay off. Sadly, it proved to be too much of a risk. By the end of the month, she was only able to pay him back £2,000, having lost £8,000.

The second woman invested in stable businesses with gradual growth, getting a steady return per day. By the end of the month, she gave the banker £1000 more than she had been given to begin with.

The third woman invested and pulled her money like a machine, shorting companies and spreading rumours to boost her profits. While she had in excess of £17,000 by the end of the month, she only returned £10,000 to the banker, arguing that everything else was not part of the deal.

Once the test concluded, the banker instantly made up his mind, and hired the woman with the biggest chest.
