Challenge ladder
Five formats, from a 12-minute signal check to a two-attempt championship case. Each level produces evidence matched to the work you actually performed.
One ladder, different questions. Short formats measure one focused signal. Longer formats let us watch how you plan, recover from setbacks, and defend your work.

Open
Can you spot when AI sounds right but is wrong?
A fast diagnostic of verification instinct. Review an AI-generated market brief, isolate unsupported claims, and decide what is safe to use.

Open
Turn an ambiguous brief into a defensible answer.
Work through a constrained client brief with a controlled AI assistant. We look at how you plan, hand work to the AI, improve drafts, and check facts — and whether you spend your limited AI budget where it matters most. Clever-sounding prompts alone won't score.

Preview
Do the work — not a quiz about the work.
A realistic research assignment with deliberately unclear parts, sources that disagree with each other, and a set limit on how much AI you can use.

Waitlist
Stay in control when the model fights back.
A multi-stage case where the AI assistant is sometimes incomplete, overconfident, or strategically misleading. Your working must stay clear enough for a reviewer to retrace.

Waitlist
A complete human-AI performance dossier.
The deepest HILArena challenge: a complex case, constrained tools, changing evidence, peer-quality review, and a live defence of every important choice.

Every level scores real work. Longer formats reveal more of how you plan, adapt, recover, and defend a decision.
