Context

Interviewers ask about SQL experience to understand both your technical depth and how you applied SQL to real work. A strong answer should show the types of queries you wrote, the scale of data you handled, and the business impact of your work.

Core question

How would you answer: "What experience do you have with SQL, and how have you used it in previous roles?"

In your response, explain:

1. The kinds of SQL tasks you have handled, such as filtering, aggregations, joins, reporting, or data cleaning
2. How SQL fit into your day-to-day work in previous roles
3. How you ensured accuracy, performance, and maintainability
4. One or two concrete examples that show business impact

Scope guidance

The interviewer is not looking for database theory alone. They want a practical, structured explanation that demonstrates hands-on SQL usage, sound judgment, and the ability to connect technical work to outcomes.
