The interviewer asks: "Why would you generate an SBOM, and how do you make it useful rather than a compliance checkbox?" Which answer best demonstrates Software Supply Chain Security Engineer expertise?
Option B is strongest because it defines the SBOM as a machine-readable SPDX/CycloneDX inventory including transitive deps, generated automatically per build from the artefact, used for rapid CVE impact analysis, licence policy, and dependency detection, and signed plus linked to provenance. Option A treats it as a write-once audit document. Option C captures only top-level deps, missing the transitive dependencies where most risk hides. Option D dismisses automation entirely, the misconception that staleness makes SBOMs useless rather than an argument for continuous regeneration and scanning.

The interviewer asks: "Walk me through the SLSA framework and what moving up its levels actually buys you." Which answer best demonstrates Software Supply Chain Security Engineer expertise?
Option B is strongest because it correctly frames SLSA as integrity levels centred on verifiable provenance, with hardening requirements like hosted isolated builders and tamper resistance as levels increase, ties it to real attacks like SolarWinds, and lays out a practical adoption roadmap with provenance verification as a deploy gate. Option A confuses SLSA with antivirus. Option C reduces it to code-review counts. Option D claims the top level means zero vulnerabilities, the misconception that build integrity equals the absence of vulnerable code.

The interviewer asks: "How do Sigstore and Cosign fit into signing your artefacts, and why is keyless signing appealing?" Which answer best demonstrates Software Supply Chain Security Engineer expertise?
Option B is strongest because it accurately describes Cosign keyless signing via OIDC identity, Fulcio short-lived certificates, the Rekor transparency log, identity-matching verification, admission-controller enforcement, and signing SBOMs and attestations too. Option A relies on a single long-lived key on the build server, exactly the key-management risk keyless avoids. Option C reduces signing to a download checksum, missing authenticity and identity. Option D claims keyless means no cryptography, the misconception that it trades security for speed when it still uses certificates, signatures, and a transparency log.
4 / 10
The interviewer asks: "What is a provenance attestation and how does it get used to make deployment decisions?" Which answer best demonstrates Software Supply Chain Security Engineer expertise?
Option B is strongest because it defines provenance as a signed in-toto/SLSA attestation recording source commit, builder identity, build parameters, and artefact digest, then shows it enforced by a policy engine that checks repo, branch, builder, and digest before allowing deploy. Option A reduces it to a commit message with no integrity guarantee. Option C confuses provenance with a user-facing changelog. Option D claims attestations can't be verified or enforced, the misconception that ignores policy-engine gating which is precisely their purpose.
5 / 10
The interviewer asks: "How do you defend against dependency confusion, and how does the OSSF Scorecard help your overall posture?" Which answer best demonstrates Software Supply Chain Security Engineer expertise?
Option B is strongest because it explains the attack precisely and defends with namespace scoping, internal-registry-only resolution, version pinning with integrity hashes, name reservation, and a single trusted mirroring proxy, then uses OSSF Scorecard to measure and prioritise hardening across repos and dependencies. Option A relies on developer vigilance, which is not a control. Option C auto-upgrades to latest, which actually increases exposure to malicious higher versions. Option D wrongly assumes popular registries prevent name collisions, the misconception at the heart of dependency-confusion attacks.

Review Comment: 'This commit introduces a new dependency, node-gyp. I'm seeing it's not listed in our SBOM. Can you explain the rationale for adding this and how we've verified its source?'
Which of the following is the MOST appropriate response to this code reviewer?
The interviewer wants to see if you understand that generating an SBOM isn't just about ticking a box. Acknowledging the reviewer's concern and stating immediate action (updating the SBOM) demonstrates proactive security practices. Options A and D are insufficient as they don't address the core issue of verification.

Slack Message from Alex (DevOps Lead): 'Hey team, we're seeing a spike in vulnerabilities reported by our SCA tool. It's primarily focused on outdated versions of lodash and moment. Can anyone quickly run a scan with npm audit --audit-level=moderate and share the output?'
Which response best shows you understand how to approach this situation?
This scenario tests your ability to react to SCA alerts. A proper response involves running the scan, documenting findings (crucial for tracking), and escalating to the security team for appropriate remediation—a key role of a Software Supply Chain Security Engineer. A simple update or ignoring the alert is not sufficient.
8 / 10
PR Description: 'Updated react-native-vector-icons to version 9.52.0. This was done as part of a routine dependency update and doesn't introduce any new security vulnerabilities. The updated SBOM has been generated and committed.'
Which statement BEST reflects the level of detail expected in a secure PR description?
The goal here is to demonstrate that you understand more than just a simple update. A strong PR description should include verification steps (source confirmation, SBOM inclusion), and ideally mention using the SCA tool for further validation - reflecting proactive security practices.

Standup Update from Ben (Developer): 'I've been working on integrating a new third-party library for image processing. I've built it locally and deployed it to our staging environment. I haven't yet implemented any security checks around the origin of this component.'
Which action should you suggest to Ben as the MOST important next step?
Ben's statement highlights a critical vulnerability: lack of provenance verification. As a Software Supply Chain Security Engineer, you need to emphasize the importance of verifying the library's origin and implementing appropriate controls (like signing) before deployment – this is core to preventing supply chain attacks.

Scenario: Your team is deploying a new microservice. The CI/CD pipeline utilizes automated artifact signing with Cosign. During deployment, the system reports a failed provenance attestation due to an unexpected change in the build metadata.
Which of the following actions should you prioritize?
A failed provenance attestation is a serious event. The priority is understanding *why* it failed – this could indicate a compromise in the build process or a misconfiguration that needs immediate attention. Rolling back without investigation could mask a deeper problem.

How many questions are in this interview set?
This set has 10 exercises, each with a full explanation.
Is this exercise free to use?
Yes. Every exercise on CoderSlingo, including this one, is free to use with no account, sign-up, or paywall.
Do these exercises include model answers?
Yes. Each interview question gives you several possible responses and asks you to pick the one that communicates most clearly and completely — the explanation then breaks down exactly why that answer works, including the specific vocabulary a strong candidate would use.
What if I choose an answer that isn't the strongest one?
You'll see which option was correct and read a full explanation of why it's stronger than the alternatives, plus the key vocabulary and phrasing worth reusing in a real interview.
Can I retry the questions?
Yes — use the "Try again" button on the results screen to reset and go through the set again.
Is this the same as a real technical or behavioural interview?
No — it's focused practice for the language side of interviewing: recognising which phrasing sounds precise and confident versus vague, and knowing the vocabulary interviewers expect for this role. It won't replace mock interviews, but it builds the vocabulary you'll need in one.
