You'd be Ashamed to Admit You Work There
One question you really need to ask yourself before accepting any new position is, "Do I really want to work for this company?" It's an important question to ask, because at some point, other people are going to want to know where you work.
Say you're at a cocktail party six months down the road. A friend comes up to you and asks, "So, where are you working these days?" Would you:
A. Lift your head proudly and exclaim, "The John Smith Company. I love it!"
B. Quickly mutter, "The John Smith Company."
C. Drop your head and mumble, "Uh, you know...Hey, is that Sharon over by the bean dip?"
Your job should be a source of pride, not embarrassment. If you're humiliated by the very idea of working for this company for any reason, cut the interview short and look elsewhere.
