Example questions or scenarios:

• "Given this dataset, write a query to identify the top three categories by volume."
• "How would you optimize a slow-running query?"

Problem-Solving and Case Studies

Be ready to go over:

• Communication of Results: Summarizing findings for a business audience.

Example questions or scenarios:

• "How would you measure the success of a new product feature?"
