Technical Skills

1. Can you explain how you would approach writing a detection for a phishing attack?

This question assesses your understanding of phishing threats and your ability to create effective detection mechanisms.

How to Answer

Discuss the steps you would take to analyze the phishing threat, including identifying indicators of compromise and the technologies you would use to create the detection.

Example

"I would start by researching the latest phishing tactics and identifying common indicators such as suspicious URLs or email patterns. Then, I would use regex to create a detection rule that flags emails containing these indicators. Additionally, I would implement a feedback loop to refine the detection based on false positives and evolving tactics."

2. Describe a challenging project you worked on related to threat detection. What was your role?

This question evaluates your experience and ability to handle complex projects.

How to Answer

Highlight a specific project, your contributions, and the outcomes. Focus on the challenges faced and how you overcame them.

Example

"In my previous role, I led a project to enhance our malware detection capabilities. I faced challenges in integrating new detection algorithms with existing systems. By collaborating closely with the development team, we successfully implemented a hybrid approach that improved detection rates by 30%."

3. How do you stay updated on the current threat landscape?
