Hey PH 👋 Every hiring manager I know has one: the candidate who interviewed brilliantly and turned out to be a mistake. Three months in, you ask yourself *"how did I not see that?"* - and the honest answer is: because nobody ever let you practice seeing it. Candidates have a hundred prep tools. The person *asking* the questions learns by shadowing and by making expensive mistakes on real people. So I built the gym for our side of the table. Every AI candidate in HiringGym is secretly assigned one of 16 behavioral personas - patterns like The Embellisher (real projects, inflated role) or The Blame Shifter (every failure has a villain) - and it actively **masks** the trait. It's competent, likable, handles deep technical and behavioral probing, and it will not confess. ou interview, take notes, make a real hiring call. Then the **Tell Report**: what your candidate was hiding, the signals that were on the table, the questions that would have popped it, and a six-dimension scorecard quoting your own transcript. Over sessions you can watch your catch rate actually move. Your first practice interview is free - no card. The reveal is the paid part, and you'll only hit that decision after you've already made your hiring call, which is exactly when you'll want to know. Two things I'd love from this community: how convincing did your candidate feel, and did you catch yours? (No spoilers in the comments, please 😄)
