People should, ideally, have a level of passion for what they do. Employers looking for employees with passion can swing too far the other way. We shouldn't kid ourselves that money is almost always almost everything, and many of us would have entirely different occupations without financial dependence.
If you are led to believe it is different, you are most likely being misled, for example in order to pay you less (as you pointed out before).
I actually find this sort of "company culture" that demands your whole being to be creepy bordering on totalitarian.
It’s not enough that you’re damn good at your job, you have to be “passionate”!
Dear employers, most of your stuff is mundane and boring. But that’s perfectly fine! If you pay us we will do our jobs very well. However, if you want us to be passionate about integrating the n+1-th tracking library into a website, or writing that ETL script, then be prepared to be lied to.
