The WorldQuant is moving their research group from NYC to some Asian developing countries where they found people there can work out high performance with relevant low human cost. Let us talk about the hiring process. They collected the resumes and sent invitations to some people they interested in for Round 1 paper test. They will get in touch with the people they are willing to move forward. After this it is several rounds of telephone interviews, all brain teasers or classical probability problems.
