Criterion
The AI interview coach that shows its work

Practice the interview.
See exactly how you're scored.
Then argue with it.

Most interview tools hand you a number. Criterion shows you the exact words behind every score — and if you disagree, you can challenge it and watch it re-evaluate, live.

How it works

1

Answer real questions

A live interviewer adapts to what you say — typed or spoken. No trick questions, no hidden rules.

2

See the standard

Every score links to the exact words you said that earned it. Nothing is scored against something you can't see.

3

Challenge the score

Disagree? Make your case and watch the score re-evaluate in the open — up, down, hold, or sent for human review.

This is the whole idea — try it

A score you can talk back to

Here's a real score from a practice interview. You think it's too low. Challenge it.

Re-reading the transcript for missed evidence

Roughly 1 in 4 challenges hold or lower the score — it's a real re-evaluation, not a rubber stamp. Reset demo

Every point traces to a quote

No black-box numbers. Click any score to read the words behind it.

Honest about uncertainty

Low confidence means "show me more," not "you failed."

Knows when to defer

When evidence can't settle it, it asks for human review instead of faking certainty.

Let's set up your interview

Two quick choices, then you're in. You can change anything later.

1 · Pick a role

Senior PM

Behavioural + product sense

Software Engineer

Behavioural + system design

Product Designer

Craft + critique

2 · How do you want to practice?

Video call

Like a real remote interview. Camera optional.

Voice

Speak your answers, no camera.

Chat

Type at your own pace. Calm, low-pressure.

Video is for practising presence and nerves — you're scored on what you say, never how you look or sound.

3 · What we'll look for

Adds up to 100%

This is the entire basis for your score — shown before you start, not after. Tweak the weights if a real interview would emphasise things differently.

You're scored on what you say — not how you look or sound.

Your camera stays on your device — nothing is uploaded in this prototype. Delivery notes (pace, filler words) are available as opt-in coaching and never touch your score.

Delivery notes Optional · never scored
Practise presence and nerves. Coaching cues from your camera — separate from the rubric, never part of your score.

Steady. You looked away mainly while thinking.

You said "blame onboarding," then corrected yourself with data. What did the post-aha drop-off tell you about the assumption the whole launch was built on?

The one thing to work on next

Volunteer the risk in your own plan

Your weakest area was Self-awareness — and it's the score that held when you challenged it. You named tradeoffs when prompted, but rarely before being asked. Next time, get ahead of it: "Here's where this could go wrong, and what I'd watch."

Final score

7.4

out of 10 · all scores firm & evidence-matched

Strongest signal

You updated your diagnosis with data in real time (Q3). That's the moment a strong interviewer remembers.
