Absolutely no questions about myself or why I wanted to work there. The interviewers did not seem to be bothered to know me, just how well I could answer tough mathematical modelling questions on the spot. They will ask you 3-4 of these, which you will have to work out in pen and paper and then hold up your solution to the camera for them to copy down. I've experienced bad interview processes before (I interviewed in Oxford for string theory PhD several years ago so go figure) but nothing like this. As said in an earlier review, no discussion about my answers, only 'is there anything you'd like to add?' at the very end.
