Most SQL Tests Miss the Point
Queries are too basic

Simple SELECT statements do not reflect real data complexity
No real datasets

Candidates are tested on toy problems, not messy production data
No visibility into approach

You see output, not how queries were built or optimized
Hard to evaluate at scale

Manual review of queries is time-consuming and inconsistent
