The interview process was very professional. Probably the best HR team I have encountered so far. Make sure that you apply as early as possible or get in touch with the recruiters as the applications close at some point. There is one on-campus round and a day of onsite interviews. Interviewers ranged from new grad to senior people and they were all very polite and helpful. The questions are challenging and unique but very fun. They have very nice offices too. I would recommend this company to all top tier maths/physics/cs students with little/no finance experience who want to get into quant trading/research.
