Your question is Salesforce Security and Trigger Recursion. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain your understanding of Salesforce security and how you would handle trigger recursion.
Keep your answer focused on how Salesforce enforces access control, sharing, and field-level security, then explain how you would prevent recursive trigger execution safely. Call out the tradeoffs between correctness, maintainability, and avoiding privilege or data-integrity bugs.
