• Network Scanning – Utilizing Nmap for discovery, port scanning, and vulnerability identification.
• Incident Triage – How to prioritize alerts, distinguish false positives from true threats, and escalate appropriately.
• Advanced concepts (less common) – Writing custom SIEM detection rules, automated playbook creation, and malware reverse-engineering basics.

Example questions or scenarios:

• "You notice an unusual spike in outbound traffic on port 53. How do you investigate this using Wireshark?"
• "What Nmap flags would you use to perform a stealth scan on a target network, and why?"
• "Walk me through your step-by-step process for investigating a suspected phishing email reported by an employee."

Cultural Alignment & Scenario Navigation

At Domino's, cultural fit is weighted just as heavily as technical prowess, especially within the high-stakes environment of security operations. We evaluate your ability to remain calm under pressure, communicate effectively, and collaborate with leadership. Strong candidates demonstrate humility, a willingness to learn, and a proactive approach to team success.

Be ready to go over:

• Cross-Functional Communication – Translating technical security risks into business impacts.
