First round: casual chat with HR about background and resume, why company, asked about decision making with incomplete information. Pretty chill with no technical questions or brain teaser. There are two rounds afterwards that I have not yet completed, still in progress.

(Chicago) I applied online. First an Online Assessment, Second a zoom interview with a recruiter, Third, a shared screen technical interview with a quant researcher. I got rejected here. But following this they will have an in-person interview at their office.

The quants are freshly graduated from bachelor or master, so if you have a PhD, dont bother applying there! also they might have a positive bias for indians (most of the quants are from there) About the process: First there is a hackerrank test, combination of probability, leetcode style and pandas questions. Then there is a phone interview with leetcode and probability questions. And finally on-sight, where they ask questions similar to the previous rounds. OLS, general questions on time series modeling for trading, some easy/medium leetcode and pandas. remember basics of ML and data preprocessing.
