I don't think you can tell the difference. But does it really matter? You work there, you build the best things you can, maybe get a promotion or two, then you move on. Or you just work there, put in four to eight hours a day and move on. Or a combination of both. Does it actually matter of the company was successful (assuming you don't have equity)? You still got the experience and knowledge and that is something no one can take away. I've learned more at my current job (year 7) than 7 years working at over a dozen companies prior to that. The author makes a good point about this. So I'm not sure why it matters if the company has scruples or is successful in the long term.
