WorldQuant interview questions

The OA consists of 3 hours 40 math questions including probability, brain teasers, linear algebra, statistcs, algorithms, geometries. no break, not very hard, but not easy at all. The most difficult problems are the geometric ones.

First step was a coding test comprising of probability and some basic coding questions. They are doable if you have practiced beforehand. Then subsequently are rounds of technical interviews with various quant researchers. They ask your experience and also test some standard quant interview questions such as probability or machine learning questions.
