Welcome to your interview.
The question is on your right: Accurate Excel 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.
How do you ensure accuracy when analyzing large, messy datasets in Excel for Walgreens reporting and analysis?
