Welcome to your interview.
The question is on your right: Advanced Excel for Analysis. 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.
Walk me through your advanced Excel capabilities. What formulas and functions do you rely on most for data analysis?
