DRW Quantitative Trader interview questions

Incredibly tough and slightly condescending interview, i appreciated i needed to problem solve but felt as though i was being made to feel stupid. The test was challenging though so I guess to be expected

Really inefficient recruitment team. If you do not like me, just give me a QUICK rejection, PLEASE! By the way, online exams are easy, totally 6 questions need to be done within 45 mins, not big deal as long as you are good at math.
