Your question is Choosing an Approach for Large Data. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to decide how to structure or organize a large, messy dataset for analysis when the right approach wasn't obvious. Walk me through how you evaluated the options, communicated your recommendation, and what impact it had.
