I applied through a recruiter. I interviewed at WorldQuant
Interview
First,sent my CV to HR
1.written test
2.on site interview
3.phone interview
all of them are brain teaser and probability.
I thought I answered all of these questions.
The hiring process was tooooooo long, I waited for about two or three months, they should know not anyone can waste time only for their special recruiting process, so I declined the offer when they come to find me.
By the way, Salary is not attractive compared to other software company, if you want to grab some talent people, you should speed up your step and don't regard them as nothing.
Interview questions [1]
Question 1
nothing special but some brain teaser and difficult probability
I applied online. The process took 2 months. I interviewed at WorldQuant in Nov 2025
Interview
Screening -> Online tests in math (many problems on a variety of topics) and programming (3 easy problems on data parsing and filling in gaps) -> 3 technical interviews (math, programming, and DS/finance), usually a few simple warm-up questions and 2 more difficult problems to test the depth of knowledge -> interviews with teams, talk about your experience, scientific work, then questions related to the specifics of the team you are applying for, you need to come up with hypotheses about the data -> rejection

Question 1
The team interview included questions from the Green Book. The questions from other stages were unique but fairly straightforward, with the exception of one that asked about knowledge of mathematical induction.
I applied online. The process took 2 months. I interviewed at WorldQuant (Thành phố Hồ Chí Minh)
Interview
There were 5 rounds in total. It began with a 30-question math assessment on HackerRank, followed by two face-to-face interviews focused on probability. Next, I completed a 24-hour take-home test and presented my findings. The process concluded with a final interview with a manager to assess cultural fit.
