I applied online. The process took 4 weeks. I interviewed at Schonfeld (Summit, NJ)
Interview
Spoke with all the members of the quant research team one by one and then took a written test. Mostly statistics questions like deriving OLS and some programming questions. Overall, it was a good experience.
45 minute view interview. Questions were about how to avoid overfitting, Machine Learning and any past projects I've done. I was given a task and had to explain how to code it in Python
The interviewer was kind and asked me some questions about regression and basic statistical problems. Not very hard but still need to be well prepared. And after technical interview, there would be a Q&A session and you can ask the interviewr questions.
