“An INNER JOIN returns only the rows where there is a match in both tables, while a LEFT JOIN returns all rows from the left table and the matched rows from the right table. For instance, if I have a table of customers and a table of orders, an INNER JOIN would show only customers who have placed orders, whereas a LEFT JOIN would show all customers, including those who haven’t placed any orders.”

This question assesses your practical experience with SQL and your ability to handle complex data retrieval tasks.

This question assesses your analytical mindset and problem-solving skills.

2. Describe a project where you had to work with cross-functional teams. How did you ensure effective communication?

Collaboration is key in data roles, and interviewers want to know how you facilitate it.
