WorldQuant interview questions

Applied online to Worldquant at two different branches. First contact was almost immediate. Took a while for one branch to realize they couldn't hire internationally but only nationals of that country. The other branch offered me the written online test (2-3 hours). If you're directly out of university (undergrad), questions are definitely doable. Otherwise (if you really want it, think again and read all posts here and elsewhere!) prepare yourself. After this two more phone "interviews" (i.e. exams). They're very rigid in the way the whole hiring process is conducted, not much respect for the applicant, people seemed intelligent without really understanding research, with this seemingly foreshadowing the working atmosphere and environment, it led me to decline the offer.
