SQL · interview question
Another engineer will maintain this code later. What choice helps the most around joins?
Multiple choiceMediumchapter-11-curatedpremiumsqljoins
Answer and explanation
Correct answer
C. Make the rule obvious in names, flow, and boundaries so the next reader does not have to reverse-engineer your intent.
Why
Maintainability comes from explicit intent. Interviewers watch whether you can explain the relational reason behind the join rather than memorizing syntax alone.
