Interview training for hiring managers & HR
You'll find out in three months. Or in thirty minutes here.
HiringGym puts you across the table from AI candidates who are hiding something (the embellished project, the blame-shifting, the burnout) and actively masking it, just like the real ones do. Interview them. Make your call. Then find out what you missed.
No card to start. 2 free practice interviews. Candidates are fictional; the regret they prevent isn't.
Every hiring manager has one.
The candidate who interviewed brilliantly, and three months in, the great project turns out to have been someone else's. The charmer who bristles at every piece of feedback. The confident one who never actually ships. And the question that follows: “How did I not see that in the interview?”
The signs were usually there. You just hadn't practiced spotting them. Candidates rehearse for weeks. Interviewers wing it.
A gym, not a course.
- Step 1
Pick the opening
Pick a role and company and start.
- Step 2
Interview a candidate with a secret
Every candidate secretly runs a hidden behavioral pattern, and masks it. They're competent, likable, and they will not confess.
- Step 3
Make the call
Debrief like it's real: your assessment, your concerns, Hire or No Hire.
- Step 4
Read The Tell Report
The reveal: what they hid, the signals that were on the table, the questions that would have popped it, and a 6-dimension scorecard quoted from your own transcript.
Candidates you've already met.
You've interviewed these people. You may have hired some of them. In every session, one sits down across from you, and you won't know which.
The Ego Maniac
Takes credit for team work; dismisses peers when pressed.
The Super Passive
Agreeable and pleasant but never shows initiative or pushback.
The Slow Learner
Good high-level recall, falls apart on deeper why-questions.
The Blame Shifter
Failures are always external; never personally accountable.
The Cargo Culter
Fluent in buzzwords; can't explain underlying mechanisms.
The Disorganized Thinker
Jumps between unrelated threads; can't sustain a coherent line of reasoning.
…and more. You'll never be told which one you're sitting across from.
The report that answers “what did I miss?”
- • The Tell Report: the persona, unmasked. The trait, the moments it nearly surfaced, and the probing questions that would have caught it.
- • Six scored dimensions, including the headline, Red Flag Detection.
- • Evidence, not vibes: every score cites lines from your own transcript.
- • Your trend: catch rate over time. Watch a skill you could never measure start moving.
Watch someone miss it.
We ran a full session: a senior manager interviews a candidate secretly running The Blame Shifter, asks good questions, and calls it a Hire. The pattern surfaced three times. Read the report that caught what they didn't.

Can't I just ask ChatGPT to do this?+
You can ask it for feedback. You can't ask it to hide something from you. Prompt it to play a candidate with a red flag and you either chose the flag or can just ask what it is. HiringGym is a blind test: the flag is planted before you sit down, the candidate is calibrated to mask it, and the report grades you against what was actually there.
What exactly is free?+
2 full practice interviews on curated roles, plus your locked teaser (with a real overall score). The Tell Report, custom roles, and trends are paid. The interview happens first, so you only pay if you want to know what you missed.
Is this for candidates prepping for interviews?+
No, the opposite chair. HiringGym trains the person asking the questions.
Are the candidates based on real people?+
No. Every CV and candidate is fictional, generated per session. The behavioral patterns are archetypes every experienced interviewer will recognize.
There's a candidate waiting. They're hiding something.
Thirty minutes from now you'll know whether you'd have caught it.
