<p>I hire summer interns in the finance industry. At the end of the summer if all works out I make an offer for full time employment after graduation. The interns are not very productive but it gives me a trial period to understand their attitudes, work ethic, and problem solving. </p>
<p>In my experience you get what you pay for. I pay interns well IMO. I have had unpaid before. Never again. Better they know they are earning a paycheck.</p>
