I was fired a few months ago from a well paying swe job; they said my performance was lacking because I was only doing my job and not more. Because the company is actually on my linkedin (they insisted on that to have my name there), my potential replacements contact me. I tell them it is nice work with quite a bit of responsibility over the technical side of their products, but they hire people (and this was true for all my colleagues) that will go the extra mile without the extra compensation. They don’t give out shares or bonuses so it’s literally without benefit. I took the position because it seemed like it was exactly that; pay for a 40 hour week, no shares, inflation indexed raise yearly and that’s it, so there is no reason to work more or over 40 hours. This expectation is pretty weird.
