To be clear, we still hire engineers who are early in their careers (and we've found them to be some of the best folks on our team).
All the same principles apply as before: smart, driven, high ownership engineers make a huge difference to a company's success, and I find that the trend is even stronger now than before because of all the tools that these early career engineers have access to. Many of the folks we've hired have been able to spin up on our codebase much faster than in the past.
We're mainly helping them develop taste for what good code / good practices look like.
