I half-agree with you, because there are some companies that use "fit" to determine how much they can use you as a "resource" rather than a human being.

Where I disagree is whether one has put themselves in a situation where they are desperate for a position at a company where they have to lie to pass the fit interview stage. I'd rather be honest and lose than lie, win and ultimately impugn my integrity.

It is very refreshing when you already have a job and are looking for something new, then you can sit back and take a relaxed approach to finding a good company. Once one is found and you are interviewing with them (and interviewing them, as a previous commenter mentioned), then you can ask all the tough questions. If you don't like what you hear, vote with your feet and walk away.

Now, this isn't always the situation people are in, so YMMV but I throw it out there as a piece of advice for anyone interviewing companies.
