I applied through a recruiter. I interviewed at 3Red Partners
Interview
Somewhat standoffish / distracted interviewer. It was a coding / technical interview but it was clear he was doing it from his phone. Asked language-specific questions, very specific data structures (in the above language) questions, algorithms questions about numpy internals, and ds&a questions.
Interview questions [1]
Question 1
What is a closure, what is a decorator, how does multiple inheritance in python work
