Byteboard

Byteboard is a technical interview platform for software engineering hiring. It replaces traditional whiteboard interviews with project-based, real-world assessments and live coding interviews that measure practical skills such as systems design, code quality, and communication across 20+ engineering competencies. Candidate work is anonymized and evaluated by trained human graders against calibrated rubrics to reduce bias and interviewer time while improving hire quality. Founded to fix the false positives, prep burden, and inequities of conventional coding interviews, Byteboard integrates with applicant tracking systems (Greenhouse) and is now part of Karat. Byteboard exposes no public developer API; this API Evangelist profile captures its company identity, web properties, domain security posture, and compliance program.

Byteboard is profiled on the APIs.io network. Tagged areas include Company, Future Of Work, Technical Interviews, Hiring, and Recruiting.

Byteboard’s developer surface includes engineering blog and 6 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/byteboard: open an issue to ask a question, or submit a pull request to add artifacts.
