Candidate Falcon
A single developer can build a usable one-way-interview practice site with AI feedback and paywall, but reproducing the product's curated content, brand reach, polished UX, and trust at scale makes a full replacement impractical for an individual.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User practices simulated assessment → record/submit response → automated AI feedback + stored performance history
What it still won’t have
- Large, curated question bank and domain-specific tuning
- Polished UX and cross-platform performance optimizations
- Brand trust and existing candidate base
- Ongoing product updates, A/B testing data and analytics at scale
- Support, refunds and compliance/legal polish
What remains hard
- Brand trust

Runnable build prompt
Build a minimal interview-prep web service using Next.js for the frontend, Node.js/Express for the API, Postgres for data, AWS S3 for video storage, Stripe for payments, and OpenAI (or compatible) for AI feedback. In scope: (1) auth (email/password), (2) question library CRUD and timed assessment runner, (3) client-side one-way video recorder with resumable upload to S3, (4) transcription (Whisper or transcription API) + LLM feedback generation pipeline that stores feedback, (5) subscription gating via Stripe, (6) simple user dashboard showing attempts and feedback. Out of scope: multi-platform native apps, large curated question datasets, analytics beyond basic charts, A/B testing, and enterprise integrations. Include input validation, retry/backoff for external API calls, secure signed S3 uploads, server and integration error handling, and automated tests for API endpoints and core business logic.
How we checked
How the score was reached
- Partly verdict base52
- 2 cited sources+1
- 3/3 assessment runs agreed+4
- Evidence score57
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
