To David Ohta:
To answer your follow-up questions:
I must state that I never held an intern-type job. I worked my way through college working at the San Diego Public Library, which provided me the money to pay for college. But I have known people who did intern work.
1) I imagine that it is more likely that an internship for a private company would turn to a full-time job. With internships with public agencies, the internship positions tend to be completely independent of full-time, permanent positions. The latter are very strictly defined and the department heads have much less freedom to simply hire a good, promising intern.
2) As to factors in deciding whether to accept a permanent position growing out of an internship....
You will have seen the "inside" of the company or department as an intern. Is the professional atmosphere a good one? Will you get along with your new boss? Is the permanent position is a Field that you really want to go into? Are you being offered a decent starting salary?
It may be that you can do considerably better by looking around and interviewing at other places, especially given the natural advantage of having worked an internship to begin with. These are things you will have to personally evaluate, yourself.
