The thing to always remember is: the way they treat you at the interview is the best they will EVER treat you.
Do they ask if you need water, coffee, etc.? Do they give you time to use the bathroom? Do they keep you waiting excessively? Do they listen to your answers and look you in the eye, or do they keep staring at the resume as if they've never seen it before?
What they say is certainly interesting, but what they do is more so.
Probably more telling for smaller companies. In bigger companies, there may be separate roles and organizations managing the interview process, and you might not interview with the exact people you work with.
True, although in my experience a long time ago, IBM was so extraordinarily considerate that I almost went to work there! They even gave me cash at the end of the interview, so I didn't have to file an expense report (unlike every other place).
I was in one office where the CEO had pictures all over his office of his collection of race cars, but the bathroom hadn't seen a coat of paint in 20 years.
I went to one little company where they had a unisex bathroom. This was not for gender equality -- it was because they had so few women that they didn't think it worthwhile to build a bathroom for them.
