The interview process involved a recruiter call, followed by technical screens which included OOP live coding questions (static method, abstract class, abstract method), discussions on the differences between LASSO and ridge regression, and questions about Python features like generators. There was also a part about portfolio rebalancing details and behavioral questions like why quant research and why Millennium.

Behavioral Technical
The interview process started with a phone call with a team quant, which was a nice chat about the role and my tech skills. After two months, I got an invite for a video interview with a strategist. This person seemed nice but hadn't looked at my resume and said they couldn't test my math skills, mentioning someone else would, even though I thought that was the last step. They also made weird comments and laughed about not getting my research. Then, radio silence. No rejection or feedback, even after I emailed the recruiter multiple times. It felt disorganized and unprofessional, a real lack of seriousness and respect for applicants, especially given their reputation. They should have sent someone qualified to assess my abilities.
