It partly depends on the job, but generally I do hate that kind of thing as it tends to mean either you are going to sit back and take a lot of chaos and pretend it doesn't drive you insane, or even worse it can be part of this whole cultural attitude that one must always be nice and anything negative is bad form. Even serious problems have to be minimized by describing them in positive words. Hey, it's a crisis here, but they want to call it an opportunity, kind of like newspeak from 1984.
On the other hand, people who complain a lot, make a fuss much of the time, whine, b***h and moan habitually and can't let anything go make life unpleasant, so that is generally not helpful. I can see that. I complain less than I used to, but I would rather address a problem rather than just pretend it isn't there, and sometimes that gets branded as negative, which is a serious culture clash. Fact is most work places are chaotic and run on crisis management and do things that make little sense -- I can see why they want people to shut up and smile, but I would rather work in a place that is proactive, progressive and well organized rather than full of such utter BS. That bugaoo called "good fit."
