About GamePrep
GamePrep is a free practice platform for HireVue-style game-based assessments. It offers 16 realistic cognitive, memory and spatial games with instant, server-scored results, percentiles and progress tracking — so candidates can walk into their real assessment knowing what to expect.
It exists because game-based assessments are unfamiliar and stressful the first time you see one, and most "practice" online is vague advice rather than the actual game mechanics. GamePrep lets you practice the mechanics themselves, for free, as many times as you like.
Independence: GamePrep is an independent practice platform. It is not affiliated with, endorsed by, or connected to HireVue or any assessment vendor. Game names describe the cognitive skill being practiced, not any specific product.
Who runs it
GamePrep is built and operated by Paweł Dziura (sole proprietorship, “Działalność Ogólna”), based in Poland. It is part of BenchKit, a small collection of focused web tools. Questions? See the contact page.
How the guides are researched
Being clear about where this comes from matters more than sounding authoritative, because the subject attracts a lot of confident guessing.
What the guides are built from: each vendor's own published material, employers' careers pages describing their process, and public accounts from candidates who have sat the assessment. Where sources disagree or a format has changed between cycles, the page says so rather than picking the tidier version.
What we do not have: access to any live assessment, its item bank, or its scoring model. No vendor relationship, no insider information, and no leaked questions or answers — not as a policy we might revisit, but because nobody outside the vendors has them and pages claiming otherwise are selling you something. Your invitation is always the authority, including over anything written here.
Where the percentiles come from: fixed norm tables we wrote, applied identically to every player and scored on the server. They are our own reference points and not any employer's benchmark — no vendor publishes its cut scores. How we score sets out exactly how a run becomes a number, including what those tables are not.
Corrections: when we get something wrong we fix it and say so on the page rather than quietly editing it. The switchChallenge guide carries one: it described a task-switching test, and the assessment is logical reasoning.
What “Last updated” means: the article itself was rewritten. It does not move when we change a page title, a description, or anything else that leaves the text as it was.
