Codehunter – helping BNP Paribas to attract tech savvy graduates

Many hidden secrets are tucked away on the internet, things that make you smile, placed there by mischievous programmers and developers. They’re known as Easter eggs, ‘in’ jokes put there by clever coders who make it their mission to add a little extra sparkle to the work they do. Exactly the kind of crowd BNP Paribas was looking to target.

CodeHunter played to that curious part of the developer personality. We began by creating four Easter eggs of our own. Then we buried them away on the BNP Paribas graduate website.

The challenge for students was to uncover them and the hidden gems of code they contained.

Once students had collected all four lines of code they entered them on a competition webpage and were then given access to the final stage of the competition. If players thought it had been tough so far, that was nothing compared to what awaited them now.

Having begun with a challenge designed to appeal to particular personality types, this was now a test of the technical ability BNP Paribas was looking for in potential candidates and designed to act as a serious filter, leaving only the brightest of the bright still in the game. The challenge was to unscramble an image by using integer maths.

If players managed to unscramble the image, they had to provide a description of it and, as is the case in pretty much every maths test, they had to show the workings they had used.

The prize? A guaranteed interview with one of the banking world’s most innovative technology teams.

The results?

248 players in just over two weeks, from two campuses and double the amount of applications for live Technology roles.
