Application

I applied through college or university. The process took 4 weeksinterviewed at WorldQuant.

Interview

They make you take an online standardized test, ater which they begin a series of interviews. The interviews were pretty variable, and depend a lot on what the interviewer's background was. Ranging from probability/dice problems to very obscure knowledge based questions such as, "Do you know Bezout's theorem? "

Some examples:
1. Given a list of N numbers you form all possible subsets of N-1 elements. You want to calculate the product of all the elements in the subset each subset. You are not allowed to use division. Provide an O(N) algorithm to do this.

2. You roll three dice, each of which can take values from 1 to 6. What is the probability that the maximum of the three rolls is p?

3. Given a random number from a uniform distribution, produce a random variable that is normally distributed.

4. Suppose the expected number of coin tosses to produce n consecutive heads is pn then find a relation between pn and pn+1.

Reasons for Declining

Seem a bit too pushy, for instance they simply set up interviews without even bothering to ask if I was available at that time. Gave me only a couple of days to decide on the offer.

Interview

Online based test. It takes about 3 months to participate in the competition and you need to compete with other people within your region to get a part-time offer. Leadboard is demonstrated on the website, so you could check how you performed compared to others.

## Quantitative Researcher Interview

Interview

My initial communication is by email coincident with their early recruitment events in my country. The first round to filter out candidate is by having all the candidates taking written exams. Then they start phone call to a subset of test takers who look promising. I had 5 subsequent phone interviews before getting job offers.

Negative Experience
Average Interview

Application

I applied in-person. The process took 1+ weekinterviewed at WorldQuant in June 2014.

Interview

The interview process had a decent flow to it and was fairly timely going from first interview progressing to the 3rd interview.

Very disappointed in the third interview due to the fact that the feedback that my recruiter provided to me was completely unrelated to anything that was covered during the interview. This leads me to believe that the individual conducting the interview either wasn't paying attention or confused my interview with another candidate.

In either case, the last interview left me wondering if I was better off not getting an offer.
