Problem

Context

Interviewers sometimes ask candidates to rate their SQL ability, but a number alone is not very useful unless it is tied to specific technical skills. A strong answer should translate the rating into concrete capabilities and limitations.

Core question

How would you rate your SQL capabilities on a scale of 1 to 10? Explain what that rating means in practical terms. In your answer, discuss:

Which SQL tasks you can handle confidently
Which areas are still weaker or less familiar
How you would justify your rating with examples such as filtering, joins, aggregations, data cleaning, or window functions

Scope guidance

The interviewer is not looking for a perfect number. They want a structured, honest explanation that shows self-awareness, technical range, and an understanding of what separates beginner, intermediate, and advanced SQL users.
