If you expect to be well compensated then you better have a strong value proposition because the world expects results! Be prepared to talk about how you delivered results with some good accomplishment stories that coincide with items listed on your resume and that illustrate the value you bring. Examples of situations where you improved desirable outcomes, or reduced or eliminated undesirable outcomes. Prove to them that you're not just another mouth to feed!
Here’s a scene from the film Ghostbusters that illustrates this point. At this point in the story, our paranormal scientist friends have just been ejected from the university. Watch as Dr. Ray Stantz (played by Dan Akroyd) explains to Dr. Peter Venkman (played by Bill Murray) about the differences in expectations of the private sector vs. the university.
