I know of at least one bigco that will no longer hire anyone, period, who doesn't have at least 6 months of experience using genai to code and isn't enthusiastic about genai. No exceptions. I assume this is probably true of other companies too.
I think it makes some amount of sense if you've decided you want to be "an AI company", but it also makes me wary. Apocryphally Google for a long period of time struggled to hire some people because they weren't an 'ideal culture fit'. i.e. you're trying to hire someone to fix Linux kernel bugs you hit in production, but they don't know enough about Java or Python to pass the interview gauntlet...
Like any tool, the longer you use it the better you learn where you can extract value from it and where you can't, where you can leverage it and where you shouldn't. Because your behaviour is linked to what you get out of the LLM, this can be quite individual in nature, and you have to learn to work with it through trial and error. But in the end engineers do appear to become more productive 'pairing' with an LLM, so it's no surprise companies are favouring LLM-savvy engineers.
