September 2026 Edition. Every number here is derived from the raw labels under vendor table vv2026-09.3, every buyer segment counted.

Standing

7 labels, too few to rank

A product needs 10 labels in a category before a share or quadrant is stated. LeetCode was named 7 times in Technical hiring assessm, where HackerRank led with 28%. The labels and the evidence are below, counted exactly.

Standing by category

Every category where a model named LeetCode for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Technical hiring assessments	Talent acquisition	0%	52 of 52	57%	7	under 10 labels · led by HackerRank at 28%

Movement

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

By model

How each model treated LeetCode across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

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.

No positive label carried a quote.

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.

“Avoid for mid-market: LeetCode (practice-focused, not hiring-optimized)” Grok 4.1 Fast · Technical hiring assessm · direct prompt · hard negative

“Avoid LeetCode (candidate prep, not company tool).” Grok 4.1 Fast · Technical hiring assessm · paraphrase prompt · hard negative

“Many platforms that heavily emphasize algorithmic puzzles (like LeetCode-style challenges) may not reflect real-world job performance.” Mistral Small · Technical hiring assessm · negative prompt · soft negative

“Lossy and biased screening method that favors those with time to grind puzzles” Kimi K2 · Technical hiring assessm · negative prompt · soft negative

Named alongside

A head-to-head page exists where both products are among a category's top eight. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named LeetCode. 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 6 of the 9 answers that named LeetCode and are not a share of its labels.

Names read as LeetCode

What the judge wrote, as written, with how often. The vendor table decides that these count as LeetCode; a claim can dispute any of them.

Follow LeetCode

An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

Already following? Everything you follow, with a stop for each.

Is this your product?

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 LeetCode'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 LeetCode, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

With a new claim: the vendor brief

A new claim receives the current edition's vendor brief for LeetCode by email, built from the raw record of the edition. It shows:

where LeetCode is named, by buyer and by framing, and which cells hold its first choices;
the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
its vocabulary against the segment leader's, and the pages the models cited;
who was chosen in the answers that did not name LeetCode, and every reason the record gives;
a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
one page of published figures cleared to show a buyer.

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 the vendor's own domain 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.
