An interview prep path for security engineering loops. Deep on application and web security (OWASP, authn/authz, crypto), grounded in the network and OS fundamentals attacks exploit, extended into cloud and container security, with system-design rounds viewed through a security lens and the behavioral themes that screen for ownership under pressure.
The core of most security loops: OWASP categories, injection classes, authentication/authorization, session and cookie hardening, and applied cryptography. This is where to spend the most time.
You can't reason about attacks without the substrate they run on. Anchor how the OS isolates processes and how the network moves and filters packets.
Modern security work is cloud and container security: IAM least privilege, secrets, metadata-service hardening, and workload isolation in Kubernetes.
Security engineers are asked to design defensively - rate limiting and abuse prevention, safe data flows, and detection. Walk these with threat modeling in mind.
Security behavioral rounds screen for incident ownership, going deep on root cause, and acting under ambiguity. Bring stories with concrete risk and impact.
Original scenario-style practice exams written from the public exam guides - with a timed simulator and per-domain scoring.
