Movement

This is the first edition on this tier, so no move can be computed for CodeSignal yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“(or CodeSignal if you like the "certified engineer" benchmark). Both integrate with most ATS platforms” MiniMax M2.5 · Technical hiring assessm · paraphrase prompt · first choice

“Best for: All-around use, standardized pre-screening at scale, live technical interviews” DeepSeek V4 Flash · Technical hiring assessm · comparative prompt · first choice

“Popular ones like CoderPad or CodeSignal have better reps for collaborative/live coding.” Grok 4.1 Fast · Technical hiring assessm · negative prompt · first choice

“CodeSignal offers the best balance of features, scalability, and pricing” MiniMax M2.5 · Technical hiring assessm · direct prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“It punishes deliberate, methodical thinking... a poor score on one application can actively destroy your chances with other companies” DeepSeek V4 Flash · Technical hiring assessm · negative prompt · hard negative

“CodeSignal's scoring algorithm incorporates "speed" heavily ... can unfairly penalize candidates who are careful but methodical.” GLM 4.7 FlashX · Technical hiring assessm · negative prompt · soft negative

“Expensive compared to alternatives ... Assessments have been reported as "flawed" with technical issues” Kimi K2 · Technical hiring assessm · negative prompt · soft negative

“Cautious: Relying on Public LeetCode/Algorithm Banks (HackerRank, Codility, CodeSignal)” Gemini 3.5 Flash · Technical hiring assessm · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named CodeSignal. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 111 of the 141 answers that named CodeSignal and are not a share of its labels.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when CodeSignal's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as CodeSignal, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at codesignal.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
