Learning / Training Made a SQL interview cheat sheet for data analyst interviews. What would you add?
Put together this one-page SQL revision sheet for analyst interviews.
I tried to cover the things that tend to matter beyond just remembering syntax: joins, aggregation grain, NULL handling, CTEs, window functions, common interview patterns, and mistakes that can quietly give you the wrong result.
For people who've actually done data analyst interviews, what SQL topic or question pattern would you add?
