Part of that is doing research and getting to know what the company looks for in candidates and what you can expect in interviews and how you meet them. Sometimes it won't be a good fit, and that's alright.

If they want you to be their monkey and that's not you, I'd say don't do it. Of course, that's very easy for me to say, but if you think it's unreasonable and don't like it, find another company. There is no "one" company --just like there is no "one" romantic partner. It's all about trade-offs.
