Data Analyst Interview Questions
Data analyst interviews test SQL almost universally, plus your ability to turn ambiguous business questions into a clear analysis plan. The biggest differentiator at the interview stage is showing you can communicate findings — not just find them.

5 Common Data Analyst Interview Questions
"Write a SQL query to find the top 10 customers by revenue in the last 90 days."
What they're really asking
Basic SQL proficiency: JOINs, aggregations, date filtering, ordering.
How to answer it
Write it cleanly with a CTE if you'd use one in practice. Adding a comment about edge cases (NULL revenue, refunds) signals senior thinking.
"Our conversion rate dropped 15% last week. How would you investigate?"
What they're really asking
Your diagnostic thinking and whether you approach problems systematically.
How to answer it
Segment first (by channel, device, geo, user segment), then timeline (when exactly it dropped), then correlation (did anything else change?). Show a process, not a guess.
"How do you present findings when stakeholders disagree with your conclusion?"
What they're really asking
Whether you can handle pushback and separate data interpretation from personal attachment to being right.
How to answer it
Show you can stay curious rather than defensive. Mention a time you changed your mind based on stakeholder context — that signals maturity.
"What's the difference between a metric and a KPI?"
What they're really asking
Whether you think clearly about measurement frameworks, not just data pulls.
How to answer it
A metric is a measurement; a KPI is a metric tied to a strategic objective with a target. The best analysts know which is which and can help teams define the right KPIs, not just report on the ones they're given.
"Walk me through a dashboard or analysis you built that changed a business decision."
What they're really asking
Whether your work actually gets used and drives outcomes.
How to answer it
This is the most important question in the analyst interview. Prepare one concrete story: what question was asked, what you found, what decision changed, and what happened after. Impact is everything.
