Welcome to your interview.
The question is on your right: Missing Data Handling. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How do you handle missing or incomplete data when conducting an analysis for marketing decisions at Northern Tool + Equipment India?
