What is AI visibility for pre-employment assessment software?

AI visibility is how often an AI assistant names a product when buyers ask which pre-employment assessment software to use. When ChatGPT, Google's AI or Gemini answers "best pre-employment assessment software", it names a short list of specific vendors — this page measures who actually appears on that list, answer by answer.

How is this measured?

We ran 4 real buyer prompts repeatedly on each engine (ChatGPT · Google AI Overviews · Google AI Mode · Gemini) on July 21, 2026, in fresh sessions, and counted which vendors each answer named — 44 answers in total. Every raw answer is published and the method is public.

Why don’t the engines agree?

They read different sources — studies show different AI engines rarely cite the same pages. That per-engine split is the finding: of the 13 vendors named at all here, only 11 were named by every engine that answered. A single blended score would hide exactly that.

Why does Google AI Overviews have fewer answers than the other engines?

AI Overviews only appears for some queries. In this measurement it appeared in 0 of 7 checks — that trigger rate is itself part of the data: it tells you how often buyers even see an AI answer on a normal Google search in this category.

Is this a quality ranking?

No. This measures MENTIONS — how often an engine names a vendor — not product quality. A great product can be rarely named and a mediocre one often. It answers "who is winning the AI shortlist", not "who should you buy".

A vendor is missing — what does that mean?

Only vendors named in at least one of our 44 answers on July 21, 2026 for these 4 prompts appear here. Not appearing means our runs didn’t name them on that date with these prompts — nothing more.

The leaderboard — each engine on its own

Vendors named in at least one answer, sorted by total mentions. Engines are never combined into one number. Stability counts flips — a prompt naming the vendor in some reruns but not others — across each vendor’s checks:

#	Vendor	ChatGPT	AI Overviews	AI Mode	Gemini	Stability
1	TestGorilla	19/20	—	10/12	12/12	flips in 2 of 16 checks

13	Bryq	0/20	—	3/12	4/12	flips in 3 of 16 checks

Mentions, not quality: this table answers “who is on the AI shortlist”, never “who is best.” Cells read “named / answers shown” per engine. Vendors not named in any answer are not listed — see the FAQ for what that does and doesn’t mean. Product aliases and sub-brands are matched (the alias set ships in the raw data).

The sources behind the answers — labeled for ownership

The domains the engines cited while building these answers. Each is labeled by who owns it — because a “ranking” cited from a vendor’s own site is a different kind of evidence than an independent one. 27% of all 303 citations in this category came from vendor-owned pages:

Domain	Ownership	Cited	ChatGPT	AI Mode	Gemini
testtrick.com	Other	21×	0	9	12
eskill.com	Vendor-owned · eSkill	13×	2	8	3
criteriacorp.com	Vendor-owned · Criteria	12×	2	7	3
imocha.io	Vendor-owned · iMocha	12×	1	4	7
reddit.com	Community / video	12×	0	5	7
gartner.com	Review platform	11×	5	3	3
cohesyve.com	Other	11×	0	9	2
bryq.com	Vendor-owned · Bryq	11×	0	3	8
vervoe.com	Vendor-owned · Vervoe	10×	2	4	4

equip.co	Other	8×	0	4	4
testgorilla.com	Vendor-owned · TestGorilla	7×	4	3	0
jobcannon.io	Other	7×	2	2	3

Ownership rule: a domain is “vendor-owned” when it belongs to a vendor in this category’s alias set; review platforms and community/video surfaces are labeled as such; everything else is “other.” We label — we don’t exclude: the raw mention counts above include all sources.

What 44 answers can — and can’t — tell you

Enough to separate consistently-named from absent from flipping on July 21, 2026; not enough to make small share differences a ranking — one run moves a vendor’s number noticeably. AI answers move continuously: this page is a dated snapshot, re-measured monthly, never a permanent verdict. We sell the measurement discipline, not placements — and we make no promise about who appears here.

Method, conflicts, corrections

The full method — prompt design, fresh sessions, alias matching, what we refuse to claim — is public: how we check. The exact prompts used here are in the published raw data.

Conflicts: CrediGeo sells AI-visibility measurement and earned-authority work. We do not sell, resell, or take referral fees from any vendor in this category, and no vendor paid to appear or influence placement. Corrections: if you believe a product was missed by an alias gap, write to [email protected] — we re-check against the raw runs and correct publicly if we got it wrong.
