EF Core Query Diagnosis Interview Practice
12 independent interview-style scenarios. Choose one best answer using each question's stated assumptions. Suggested study time: 22 minutes, with no countdown. One point per correct answer; zero for incorrect or unanswered questions. Review every explanation and revisit the cited section. No pass threshold; this is study practice, not a validated measure of hiring readiness. Code, SQL, and service behavior require verification on the target runtime/provider; these questions are design exercises, not reports of executed integration tests.
- Answers save as you go. Move between questions freely, and mark any to come back to.
- No time limit: take as long as you need.
- Keyboard: press A–D to choose an option; ← and → move between questions.
