The process took 1 week. I interviewed at WorldQuant
Interview
Sent CV and recieved an invitation for online test. Online test can be quite difficult if you are not prepared since it has strict time limit and answer should be accurate. It may be doable for students or who just finished undergradute. Includes lots of coin problems, calculating expatation, time complexity of algorithms,finding result of pseudo code etc.
I applied through a recruiter. I interviewed at WorldQuant in Aug 2014
Interview
five interview with different levels: through online test, with local employees, with senior employees at headquarter, personality test, background check and compliance test. Very fast and accurate. I highly appreciate the support from HR team
First, when you passed the cv review, you will be invited to online math/logic test - the test will be timed each question. it isnt difficult but you have time pressure
If you pass online-test, then will invited to pre-screening phone interview and series of brainteasers. Brainteasers are very hard, you need to prepare for it.
