AI has made even worse an already broken hiring https://hbr.org/2026/06/ai-has-broken-hiring-heres-how-to-fix-it
AI Has Broken Hiring. Here’s How to Fix It.

Generative AI is rapidly undermining the reliability of traditional hiring signals, making it easier for candidates to manufacture polished rƩsumƩs and perform convincingly in remote interviews with real-time assistance tools. Interviews with 120 talent-acquisition leaders and an analysis of more than 6,000 screening sessions show that companies now risk selecting for candidates who are best at navigating the hiring process rather than best equipped to do the job. To adapt, organizations must redesign early-stage hiring around authentic reasoning, judgment, and adaptability instead of static credentials and scripted interviews.
