My last job had a team with about 50% temp and contract. When the LLMs got popular, I could tell right away. When I reviewed their code, it was completely different than their actual style. The seniors pushed back because it was costing us more time to review and we knew it was generated. Also, they couldn't talk about about what they did in meetings. They didn't know what it was really doing. Eventually the department manager got tired of our complaining and said "it's all inevitable." Then those mercenaries started to just rubber stamp each other's PRs. The led to some colossal fuckups in production. Some of them were fired quietly, and the new people promptly started doing the same thing. Why should they care, it's just a short term contract on the way to the big payday, right?
