Editorial policy

PentestLab publishes original guides written by an editor with direct experience in tech interview & security careers. We do not accept guest posts, paid placements, or AI-generated filler. Every guide is reviewed against current public-source evidence before publication; pricing and platform data refresh at minimum quarterly.

Where this site links out to the parent product JobHunterBot, those links carry rel="sponsored noopener" and a UTM tag, per the anti-PBN link-hygiene policy defined in Epic 9 Story 9.14. Theme-adjacent satellites cross-link only when the linked material is directly relevant; non-adjacent satellites do not link.

Content sources & corrections

Sources are cited inline with the link text identifying the publishing organisation (e.g., "Harvard Business School", "Glassdoor Transparency Report", or the ATS vendor's own documentation). Outdated or incorrect facts get a correction edit and a `lastmod` front-matter bump so readers and crawlers see the update date on the page.
