Network Security Engineer interviews — common questions

Who is this Network Security Engineer interview plan for?
It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Incident Response Q&A round for a Network Security Engineer role. It gives you a 60 min script to follow in the conversation — 7 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.
What does the Incident Response Q&A round assess?
This round is focused on: Incident Response, Threat Mitigation, Security Monitoring, Alert Management, Disaster Recovery. It works through Introduction, Technical Q&A and Closing, scoring against 45 observable signals, with follow-up prompts on all 7 questions for going deeper where an answer is thin.
How is the 60 min split up?
Introduction (5 min), Technical Q&A (50 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.
