It's training contract interview time in the City, and Tulkinghorn is in a position to give all those spotty 20-year-olds a top tip.
There's a running joke at one top 10 firm that the partners will offer any nervous wannabe a place if they literally take the biscuit. In other words, they reckon that if a student has the balls to reach over and take some of the scran on offer during their grilling, they'll also have the right stuff to do all-nighters.
Another top tip, apparently, is fizzy water. No one ever asks for it, but they should. So if any of this year's intake start quaffing Perrier and grabbing all the grub, you'll know why.
