I batch-analyzed 200 tech listings with Claude API and found 23.5% were ghost jobs. So I built GetDiogenes to spot them automatically.

Wait 5 sec.

Hey r/SideProject, Like a lot of devs looking for work, I got sick of spending hours tailoring applications for job postings that were abandoned or posted months ago. To see how bad the problem actually was, I wrote a TypeScript script to pull 200 recent software engineering listings off the Adzuna API and run them through Claude to check for ghost-job red flags. The Results: - Total analyzed: 200 - High-risk ghost jobs: 47 (23.5%) - Avg risk score: 33.6 / 100 Top Red Flags Found: Evergreen Duty Boilerplates: Postings reading like a generic CS textbook with zero team/stack specifics. Kitchen-Sink Skill Requirements: Requiring 5+ years in 6 non-overlapping domains without senior pay. Silent Repost Loops: Roles marked "posted 2 days ago" that matched historical job IDs active for 90+ days. I turned the detection prompt into a web app called GetDiogenes (https://getdiogenes.com) to help job seekers check listings, evaluate ATS fit, and practice mock interviews before applying. We run on a pay-as-you-go credit model (no recurring subscriptions), and you get 3 free credits on sign-up. Would love to hear your thoughts on the scoring metrics or feedback on the site!   submitted by   /u/GetDiogenes [link]   [comments]
