I agree, Ken. Good time to interview the Hiring Manager too, to help determine your fit in the organization. Asking questions as a potential employee is part of a healthy interview. The interview shouldn’t be a one sided street.I think that interviews ARE a place to be explaining. A career type job is one that requires a fit between employer and employee. Not just a fit between needs and skills, but also a fit in culture. When I hire someone, I am hiring the person, not their ability to draw lines in AutoCAD. And the more information I have to make a determination of who that person is, the better equipped I feel to understand how they'll fit in our corporate environment.
Furthermore, I make it clear (especially to entry level people) that THEY need to be interviewing US as much as WE're interviewing THEM. Hiring someone/changing jobs is a big deal. The more info you have the more likely you will get it right.
