PrepRun is an independent candidate-preparation platform. It is not affiliated with, endorsed by, or connected to HireVue or any employer named in its public guides. Product and employer names are used descriptively.
PrepRun brings three preparation workflows into one browser-based platform:
| Practice mode | What the candidate does | What PrepRun adds |
|---|---|---|
| Game-based assessment | Practises timed cognitive and work-style tasks | Real timers, adaptive difficulty, mistake review, focus drills, progress tracking and company-pack mock flows |
| One-way video interview | Records answers under preparation and answer timers | Camera and microphone check, editable transcript, local replay/download and answer-specific AI coaching |
| General interview coach | Prepares for a live interview using a vacancy and optional CV | Role-fit questions, adaptive follow-ups, transcript coaching and questions to ask the interviewer |
Candidates can try PrepRun in the browser before choosing a paid plan.
This is the public resource and documentation repository for PrepRun. It provides:
- practical interview and assessment preparation guides;
- a transparent explanation of the coaching framework;
- a place to report inaccurate or outdated company-assessment information;
- a public route for feature requests and product feedback;
- links to the official PrepRun platform and its research pages.
The production application and its private backend are not distributed from this repository.
PrepRun does not apply one rigid template to every answer. It first identifies the type of question and then chooses the relevant coaching criteria.
| Question type | Framework PrepRun expects | Typical coaching focus |
|---|---|---|
| Behavioural or competency | STAR or another clear evidence structure | Situation, task, personal action, result, specificity and impact |
| Motivation or company fit | Motivation, evidence, connection and forward fit | Why this role, why this organisation, credible evidence and a specific contribution |
| Tell me about yourself | Present, relevant past and future fit | Relevance, narrative, brevity and connection to the vacancy |
| Technical or knowledge | Direct answer, reasoning, evidence and limitations | Accuracy, prioritisation, explanation and application |
| Situational or judgement | Decision, rationale, stakeholders and trade-offs | Judgement, risk awareness, communication and next steps |
Feedback can include:
- an overall coach rating and category-level ratings;
- missing evidence or unanswered parts of the question;
- structure and clarity issues;
- filler-word and concision notes where relevant;
- a stronger rewritten answer;
- a delivery cue for the next recording;
- role-fit observations grounded in the vacancy;
- adaptive follow-up questions in General Interview Coach mode.

PrepRun includes practice for a range of cognitive and work-style assessment mechanics, including:
- Numerosity;
- Digit Span;
- Disco Numbers;
- Shape Dance;
- Flashback;
- Puzzle Picture;
- Pathfinder;
- Portrait and PortraitXT;
- Teamchat;
- Singularity;
- E-Motions.
Some exercises produce a level or accuracy score. Work-style exercises are treated as practice-only where a meaningful performance score would be misleading.

Record answer → transcribe → edit transcript → get coaching → answer again
The video remains local to the browser during practice. If browser transcription is unavailable, cloud transcription is only used after the user chooses that fallback.

PrepRun is designed around five practical principles:
- Practise the real interaction, not generic advice. Timers, input mechanics, camera checks and repeated answers matter.
- Ground coaching in evidence. Feedback refers to the question, transcript, vacancy and relevant answer framework.
- Do not force STAR everywhere. STAR is useful for behavioural evidence, not for every motivation, knowledge or introductory question.
- Be conservative about employer claims. Assessment formats can vary by role, country and year.
- Keep candidates in control of their data. Vacancy and CV reuse is browser-based, and local video is not uploaded as part of normal rehearsal.
Public contributions that improve candidate preparation are welcome.
- Report outdated company-assessment information
- Request a company or programme guide
- Suggest a product improvement
Please do not post invitation emails, personal data, proprietary test questions, assessment screenshots or content covered by an employer confidentiality agreement.
See CONTRIBUTING.md for the evidence standard.
Do not open public issues containing credentials, personal data or a vulnerability that could affect candidates. Follow the private reporting process in SECURITY.md.
