I applied through a recruiter. I interviewed at Root Inc. (Columbus, OH) in May 2021
Interview
The interview was split into three sections, the first was about stats, the second was about modeling, and the third was to solve an abstract thought problem which could potentially lead to the development of some pseudo code.
Interview questions [1]
Question 1
How do you calculate linear regression (i.e., what function is optimized/minimized to create a linear regression model)?
