Overview

About data science questions in quant interviews

This page collects every data science interview question on Myntbit. The 98 problems are tagged with the firms that ask them and ranked from easy to hard so you can drill the patterns in the order interviewers actually use. Data Science crosses the boundary between the math, coding, and markets sections of a typical quant round, so candidates pulling from a single track usually still encounter it.
