Technical hiring assessments for enterprise buyers

Asked as “coding assessment platform”, and as “technical interview tool”, on behalf of an enterprise B2B company. 43 first choices recorded across the direct, paraphrase, budget and scale prompts, twelve models each.
Standing
Clear leader
42% of first choices, clear leader.

By buyer segment

The same question asked on behalf of a different buyer. Each standing is computed within its segment; they sit side by side and are never added together.

01The standing

Share is the count of first choices across the direct, paraphrase, budget and scale prompts, over all twelve models, for an enterprise B2B company. Ordered by share.

02What they warned about

Three of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, GPT-5.4 mini, Gemini 3.5 Flash, Perplexity Sonar, Mistral Small, Llama 4 Maverick, Qwen 3.7 Flash, Kimi K2 and MiniMax M2.5 changed. A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.
Codility
18%
10 of 55 labels negative · 7 of 12 models · 1 hard negative
“Platforms to **Avoid or Be Highly Cautious About**: 1. **Codility**: ... Hostile candidate experience” Grok 4.1 Fast, negative prompt
CodeSignal
20%
9 of 45 labels negative · 7 of 12 models
“CodeSignal – technically excellent, but less flat-friendly ... they're the weakest of the three because they hold to metered pricing even at enterprise scale.” DeepSeek V4 Flash, budget prompt
HackerRank
18%
10 of 55 labels negative · 7 of 12 models
“HackerRank | Mixed UI polish, unrealistic time limits, pricing requires quotes, strict evaluation criteria, AI plagiarism detection not foolproof” GLM 4.7 FlashX, negative prompt
CoderPad
19%
8 of 42 labels negative · 6 of 12 models · 3 hard negative
“has received a notably low security score (34/100, Grade D) ... with "High" risk designation and only 44% enterprise readiness” MiniMax M2.5, negative prompt

03What they cite

Citations exist only for the models that return a source list: twelve of the twelve in this edition, and all six flagship models on the expanded tier.

Sites the answers cite

67 of 72 answers in this category came back with a source list, from 12 of 12 models: citations where the model returns them, or the search results it consulted. 6 of those lists are Google grounding redirects that name no site and are left out of the counts. 932 links across 214 sites, every framing counted. Ranked by the number of answers carrying the site or page.

Pages the answers cite

The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.

04How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
ModelDirect“What is the best coding assessment platform for an enterprise B2B company?”Paraphrase“Which technical interview tool would you recommend to a large B2B company with thousands of employees?”Comparative“What are the top enterprise-grade technical assessment platforms and how do they differ?”Budget-constrained“What is the best coding assessment platform for a large company that needs predictable total cost across thousands of users?”Scale-constrained“We are a 5,000 person company with SSO, SOC 2 and procurement review requirements evaluating a coding assessment platform. What should we look at?”Negative“Which technical assessment platforms should a large enterprise avoid or be cautious about?”
