Welcome to your interview for the Business Analyst role at Hubbell.
The question is on your right: Cleaning Incomplete Datasets. 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. You have three graded attempts to score 7/10 or better.
How would you approach cleaning and structuring an incomplete dataset to prepare it for analysis at Hubbell?
