Question 1

What SQL topics does Netflix focus on?

Accepted Answer

Netflix SQL interviews emphasize A/B test analysis (cohort comparison, statistical significance setup in SQL), subscriber churn and retention modeling, content performance metrics (watch time, completion rate), and complex window functions. Expect datasets around viewing sessions, subscriptions, and experiments.

Question 2

Does Netflix ask about causal inference in SQL?

Accepted Answer

Yes. Especially for Data Scientist and Senior Analyst roles, Netflix asks you to design SQL queries that compute the backbone of an A/B test — treatment vs control splits, conversion rate differences, and attribution windows. You won't run the statistical test in SQL, but you'll prep the data for it.

Question 3

How many SQL rounds does Netflix have?

Accepted Answer

Netflix data interviews typically include 1-2 dedicated SQL rounds, often paired with a metrics design discussion. Data Scientist loops may blend SQL with experimentation theory. Data Engineer loops test SQL plus pipeline/ETL thinking.

Question 4

What SQL dialect does Netflix use?

Accepted Answer

Netflix uses Presto/Trino and Spark SQL internally. Interviews accept standard ANSI SQL — window functions, CTEs, and date math work the same. Knowing DATE_TRUNC and DATE_DIFF is helpful since Presto functions come up in some live-coding prompts.
