What you get

Practise like it is the real interview

A real-time conversation

Live voice

Choose a persona, add the job description and enter a live conversational simulation designed to test your real capabilities under authentic pressure.

Hostile by design

Grill Mode

An aggressive, sceptical interviewer who hunts for holes in your CV and challenges every claim, so you can fail safely now rather than later.

Audio-only phone screens

Blind Mode

Switch off the video avatar to practise the way most first-round screens really happen. Train your voice, pacing and clarity.

S.T.A.R. and vocal analytics

Live tracking

As you speak, EnDev flags Situation, Task, Action and Result in your answers, and tallies your filler words and speaking pace.

Know your weak spots

Telemetry

Quantified scores for communication style, technical accuracy and mental agility from every session, so you can see your trajectory improve.

Turn rambling into results

The Vault

Paste raw career memories and the AI rewrites them into polished, impact-driven achievements with quantified results.

AI personas

Choose your interviewer

Jenny

Beginner friendly

Standard and friendly. Warm, welcoming and balanced pacing, ideal if you are easing into practice.

Arya

Behavioural focus

Warm and empathetic. Patient and encouraging, with deeper follow-ups that draw out your story.

Suzan

Technical deep-dive

Technical and sharp. Probes architecture, trade-offs and reasoning, built for senior engineering roles.

Charon

Final boss

Tough and executive. Hostile, sceptical and time-constrained, like the hardest C-suite interviews.

FAQ

AI mock interview questions

How do AI mock interviews on EnDev work?

You upload your CV and a target job description so the AI interviewer is aligned to your role. You then pick a persona and an intensity level and have a live voice conversation, speaking your answers out loud. Afterwards you receive a full scorecard with AI-generated model answers for every question asked.

What is the difference between the AI personas?

There are four. Jenny is friendly and balanced, good for first-timers. Arya is warm and empathetic and asks deeper follow-ups, with a behavioural focus. Suzan is technical and sharp, probing architecture, trade-offs and reasoning. Charon is a tough, time-constrained executive who mirrors the hardest C-suite interviews.

What is Grill Mode?

Grill Mode turns the interviewer into an aggressive, sceptical hiring manager who hunts for holes in your CV and challenges every claim. It is designed so you can fail safely in practice rather than in a real interview.

What is Blind Mode?

Blind Mode switches off the interviewer's video avatar to simulate an audio-only phone screen, so you can train your voice, pacing and clarity without visual cues.

Can I practise interviews in languages other than English?

Yes. EnDev supports 12 languages natively: English, Spanish, French, German, Italian, Portuguese, Polish, Bulgarian, Chinese (Mandarin), Japanese, Arabic and Hindi.

How much does an AI mock interview cost?

EnDev uses pay-as-you-go credits. A full mock interview costs an estimated 25 credits, and credit packs start at £4.99 for 50 credits. Credits never expire, and the actual deduction depends on session length, strictness and the features used.
