Using detailed LinkedIn résumé + job-posting data on ~285k U.S. firms (2015–2025) to study a debated question: how does generative AI adoption affect entry-level employment?
We identify adoption from job postings explicitly recruiting AI integrators (e.g. “we need someone to put genAI in our workflow!”). A firm is an adopter if it posts ≥1 such role.
We find ~10.6k adopting firms (~3.7%), with a sharp takeoff beginning in 2023Q1.
In the aggregate, before 2022 juniors and seniors move in lockstep. Starting mid-2022, seniors keep rising while juniors flatten, then decline.
