Technical Interviewing & Assessment: AI Visibility Ranking

Platforms for coding interviews, assessments, and engineering hiring. Right now, HackerRank is the brand AI assistants recommend most, with a Visibility Score of 71 and the #1 spot in 29% of answers. Head-to-head: HackerRank vs CoderPad →

These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.

Two brands own the category; the rest trail badly.

HackerRank and CoderPad sit close together at the top, each mentioned in over 77% of answers, while the remaining three brands cluster well below 56% mention rates with scores less than half of the leaders. CodeSignal's situation is worth watching: it scores 68 with ChatGPT but only 22 with Claude, a 46-point gap that suggests deeply inconsistent positioning across models. Codility and Karat have essentially zero first-pick presence, meaning AI models acknowledge them but rarely lead with them when a buyer asks for a recommendation.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.

Just below the cutoff: CodeInterview (3.5), Eraser (3.5), Pramp (3.2), GapJumpers (3.2), CodeSubmit (3.2). 68 brands were scored in this category; the leaderboard shows the top 15.

Visibility Score: position-weighted presence across all measured answers, 0 to 100. A score of 100 means the brand was the first recommendation in every answer. Every point in a trend line is a live monthly measurement; there is no modeled or backfilled history. Full methodology.

Openness 29/100: the share of this category's recommendation weight not held by the leader.
