Yes! Window functions and decent demonstration of datasets with varying granularity on top of the basic join/aggregation assessment is all that is needed in the SQL for interviews. And if you're an engineer, attention to redefining the query plan through appropriate use of temp tables. Anything else is a poor use of precious interview time for both parties, in my opinion
