I started out in advertising, and I felt the same way you feel. There was a sense that I was lying to people, and it bothered me. I have also taken jobs in the past that I didn’t feel 100% great about, and in the end I have never been satisfied. It also seems if you compromise once, it is easier to compromise again, and then your entire life becomes a compromise. (Okay, that may be a bit simplistic.) On the other hand, I am sure there are many happy, fulfilled people in the world who got started doing a job that wasn’t a good fit for them at all.

Here are some other questions that might lead you to some understanding: Do you like the people you have met so far? If you became more like these people, would you consider that a good thing? What would your tasks be? Do you believe in the product or service you would be marketing? If you really don’t get a good vibe from the company, do you think you could handle that for more than 6 months?
