Interview question

How would you implement an admin CRUD screen for managing a sensitive resource?

Build an admin CRUD workflow with permissions

Explains admin list/edit/delete workflows with capability checks, audit events, confirmation, validation, and recovery.

TL;DR

I would build a paged admin list with filters, row actions, and a detail or edit screen. The frontend can hide actions the current user lacks, but every API endpoint still checks capabilities. Create and update use explicit DTOs and validation. Destructive actions require a confirmation step and clear success or failure feedback. The backend records audit events for sensitive changes.

Why this question matters
Admin CRUD can look like boring scaffolding, but it often controls sensitive data and privileged workflows. A solid design treats the admin UI as a client, not as trusted backend code.

Stronger answer
Optional upgrade with examples, trade-offs, and sharper phrasing.
I would make the workflow safe for partial failure and stale data. Edits can use optimistic concurrency so an admin does not overwrite another admin's change silently. Delete may be soft delete, archive, or state transition depending on recovery needs. The UI should show what changed, who changed it where available, and whether a lockout or restriction applies. Bulk actions need preview and confirmation rather than silent mass changes.
Finish
Advanced answer
Optional deeper angle for production judgment and nuance.
In production I would add audit search, permission-aware navigation, rate limits for expensive admin operations, and support-friendly error messages. Admin pages need pagination by default because data grows. I would avoid logging secrets or large before/after snapshots, but keep enough context to investigate incidents. For high-risk actions, step-up authentication, approval, or delayed execution may be appropriate. Metrics should show failed admin actions, denied actions, validation failures, and destructive action counts.

Common mistakesCandidateCommon mistakesMistakes that weaken the answer or signal shallow understanding.Open details

Details

Trusting hidden frontend buttons as authorization.
Deleting sensitive records without confirmation or recovery.
No audit event for privileged changes.
Unpaged admin lists that will grow forever.

Red flagsCandidateRed flagsSignals that an interviewer may treat as risky.Open details

Details

Cannot explain capability checks on the API.
No stale-edit or concurrency behavior.
Dangerous bulk actions run without preview.
Audit data is either missing or stuffed with secrets.

Treat these as the next interviewer turn. Answer one out loud, then save the gap in your practice notes.

Which admin actions need audit events?
When would delete become archive instead?
How would the UI respond to a 403 after permissions changed?
