Let's say 5 or 10 years later you're applying to a job where one of these upper-level people now work. How do you want them to remember you? The know-it-all who wasn't a team player and kind of an asshole? Or the engineer who gets things done and has demonstrably shown to land impact and value, an engineer the exec would consider lucky to have?

Some of you will say you wouldn't want to work for one of these executives again. But people change, incentives change, the environment changes. Have you ever made a technical decision you later regretted?

And maybe you don't work for them. Maybe you're applying to a different company where someone knows these previous upper-level management folks and they ask about you. How do you want that recommendation to come across? "That engineer was an asshole.", "That engineer was amazing, I wish we could have kept them. We made a big mistake by not trying to keep them.".
