Find your weak axis before the loop does
Put this idea into your own words: "A clean, specific answer means lived depth; a hand-wave means a gap to close."
Step 1 of 3
Find your weak axis before the loop doesa fast self-check
Run these against yourself out loud. A clean, specific answer means lived depth; a hand-wave means a gap to close.

Advanced table
Your weakest row is where to spend prep time
- Axis
- AppSec
- Self-check question
- Walk me through finding and fixing an IDOR you actually shipped a fix for.
- What a strong answer sounds like
- A real object-level authz bug, the fix and the systemic guard you added
- Axis
- Cloud/infra
- Self-check question
- How would you grant prod access for an incident without leaving standing permissions?
- What a strong answer sounds like
- A concrete JIT flow: scoped role, time-boxed grant, approval path, auto-revoke, audit
- Axis
- Crypto applied
- Self-check question
- When do you hash vs. encrypt vs. encode and where do people misuse each?
- What a strong answer sounds like
- Clear distinctions plus a real misuse you've seen (e.g. encoding mistaken for protection)
- Axis
- Building
- Self-check question
- Show me a security tool you wrote that other engineers adopted.
- What a strong answer sounds like
- A scanner, helper or sandbox with real adoption and a precision/noise story
- Axis
- Agent security
- Self-check question
- How does prompt injection hijack a coding agent and how do you contain it?
- What a strong answer sounds like
- Direct vs. indirect injection, the tool-abuse path and a sandbox/allowlist containment
| Axis | Self-check question | What a strong answer sounds like |
|---|---|---|
| AppSec | Walk me through finding and fixing an IDOR you actually shipped a fix for. | A real object-level authz bug, the fix and the systemic guard you added |
| Cloud/infra | How would you grant prod access for an incident without leaving standing permissions? | A concrete JIT flow: scoped role, time-boxed grant, approval path, auto-revoke, audit |
| Crypto applied | When do you hash vs. encrypt vs. encode and where do people misuse each? | Clear distinctions plus a real misuse you've seen (e.g. encoding mistaken for protection) |
| Building | Show me a security tool you wrote that other engineers adopted. | A scanner, helper or sandbox with real adoption and a precision/noise story |
| Agent security | How does prompt injection hijack a coding agent and how do you contain it? | Direct vs. indirect injection, the tool-abuse path and a sandbox/allowlist containment |
Your weakest row is where to spend prep time. If two rows are weak across different axes, start with the cloud/infra one - AppSec candidates fail the dual-domain bar there most often.

Optional practice
Practice: Find your weak axis before the loop does
QYou have eight years of strong application-security experience but your cloud/infrastructure security is thinner - you've used IAM but never designed a JIT access system. How should you handle that against this role's dual-domain bar?
