About your past

Describe a threat hunt you ran. What was your hypothesis and what did you find?

What they are checking: Whether they hunt from a clear hypothesis and turn findings into better detections or fixes.

Tell me about a time you got lost in deep research on a technical problem. What came out of it?

What they are checking: Whether their curiosity leads to useful results, since the posting openly looks for that trait.

What would you do

You're mid-investigation at 7 p.m. and need help from a teammate in another region. How do you hand off cleanly?

What they are checking: Whether they document well enough for global teammates to pick up a case without starting over.

The business owner of a compromised server refuses to take it offline during trading hours. What do you do?

What they are checking: Whether they can weigh containment against business impact and escalate properly instead of acting alone.

This role starts on second shift, 12 to 8 Central. How does that schedule work for you?

What they are checking: Whether they've honestly considered the shift the posting states before accepting the role.

About the work

Walk me through how you'd handle a medium-severity alert for suspicious PowerShell on a workstation, from triage to remediation.

What they are checking: Whether they can run the full incident response lifecycle in order, without skipping containment or evidence.

What artifacts do you look at first in endpoint forensics on a Windows machine, and why?

What they are checking: Whether they know where evidence of execution and persistence lives, like prefetch, event logs and registry keys.

How would you safely analyze a suspicious file you pulled from an endpoint?

What they are checking: Whether they know static and dynamic malware analysis basics and isolate samples properly.

How does incident response change when the compromise involves a cloud account instead of a laptop?

What they are checking: Whether they're ready for a multi-cloud environment, where identity and API logs replace disk images.

Tell me about a tool or script you built with Python and a REST API to speed up investigations.

What they are checking: Whether they can automate their own work, which this role lists alongside response.

How do you know when an incident is actually over?

What they are checking: Whether they confirm eradication and root cause rather than closing a ticket once alerts stop.
