Welcome to your interview.

The question is on your right: Understanding SQL Triggers. Take a moment with it first.

Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.

Problem

What is a trigger in SQL? Explain its purpose, how it operates, and provide examples of scenarios where triggers are beneficial. Additionally, discuss the potential drawbacks of using triggers in a database environment.

Scope Guidance

The interviewer expects a clear explanation of triggers, including their types (BEFORE, AFTER, INSTEAD OF), how they are defined, and common use cases such as enforcing business rules, maintaining audit logs, and automating system tasks.
