I applied through a recruiter. I interviewed at Citadel
Interview
Started with online assessment (questions about pandas and SQL data manipulation). After passing that test, the second stage was a live interview on statistics followed. The recruiter had mentioned that the second stage would be about coding, so I prepared for it (didn't expect much of stats questions). Didn't move forward after that.
Interview questions [1]
Question 1
- Extract data details from pandas df.
- Textbook statistics questions about random variables (expectation, variance, etc.).
