For me it's the opposite. When I interview some of the things I look for: - Are they comfortable and productive in their own coding environment? - Do they understand the code they are writing? There are more things I look for, but those two touch upon this... if someone interviewed and were fluently moving around their coding environment and the quality was high and they understood what they were doing (complexity, allocs, maintainability, readability, approach to the problem, etc)... then they'd be hired. Further, their future perf reviews would never care about this stuff. Or if it did, it's only to say that this is part of the health and wellbeing of the individual who has chosen a work environment in which they are happy and productive - which is a net positive to the company.
