Escalate unresolved or systemic issues to the L3 engineer with clear documentation of findings and attempted fixes
Compliance & Reporting

Ensure all changes, incidents, and maintenance tasks are fully documented in ServiceNow

These emails may request recipients to provide personal information or to make payments as part of their illegitimate recruiting process.
