The Interviewer is Evasive
You can learn a lot about a position (and company) from the hiring manager's words and body language. Is she answering your questions directly, or does she keep changing the subject? Does she make eye contact and address you directly, or mumble her responses at the window? You want a manager who will be open and honest with you, not one who will evade your questions.
Your wishy-washy interviewer is signaling that there's a big issue with the job. Maybe the position is so awful that she can't be straight about it. It could be that the company's health benefits are miniscule or the hours are grueling. If you can't get a straight answer, head straight back to your job search.
