I like to not think of anything as “absolute” or “dealbreaker” (within reason. If there’s a culture of harassment I’m gone, for example). But spend intentional time throughout your career reflecting on what matters to you in terms of team culture, code culture, career growth opportunities, compensation, etc. There are a lot of factors to being happy in your work, and a lot of ways to get there. Be intentional about it, and try to always move toward it. It matters a lot more than whatever software you’re writing.
