I applied through college or university. The process took 2 weeks. I interviewed at WorldQuant
Interview
Phone Screen was straightforward. First there was a resume-based question. They asked me about my work in deep learning and then had me explain a neural network and backprop to them. Next was a fairly simple math question about something to do with the variances of two random variables. Hadn't done any algebra in a long while so I quite embarrassingly failed.
Interview questions [1]
Question 1
Explain how neural networks and backpropagation work.
First stage is an online test comprised of 40 questions. The test is about 3 hours long and there is a break you can take after 20 questions answered.
Next stage is a 3 hour interview with 2 researchers of the company.
I applied online. The process took 1 week. I interviewed at WorldQuant (Budapest) in Jun 2021
Interview
Mostly, the questions related to Algorithms and Probability were asked. In addition to them, basic Finance and Stock Market-related questions were asked as well. The manager was in very positive attitude and was very frank. He properly answered my questions at the end as well.
