I worked for Optiver (largest marketmaker in Europe) between 2007 and 2010. We hired grads for trader positions all the time.

Optiver even sponsored the mathematic, physics and cs study association for students in Leiden for the longest time. Trying to win over students before they graduated.

Competitors did this too. Really nothing new here.
