There's a spectrum of process from cowboy to multi-decade space mission, and as an experienced engineer, I know where I want to be, and I can grudgingly accept that other places on the spectrum can be appropriate if there's a real business justification.
Since it sounds like you're more on the cowboy side of the spectrum, one thing to be aware of while you're interviewing is that 'best practices' seems to be more process, so when you ask, most people aren't going to just come out and say they YOLO editing PHP on prod... you've got to ask and refine your probing questions so that you get to something close to accurate, while sometimes not revealing your preferences.
The other thing is that generally, the more experience and tenure you have, the more clout you have to skip process. Skipping meetings has consequences, of course, but sometimes it's better for you to have an hour of sanity and accept that decisions will be made without your input. IMHO, when you intentionally skip meetings, you should not re-litigate the decisions of the meetings, unless they're really infeasible or damaging to the business.
