Context: I've studied Biochemistry and while working in a lab I've studied Computer Science parallel.
As programmer I've done a (paid) freelancer project which involved exactly the technology the company is using for which I'm going to apply.
I'm now in the process of preparing for interviews and my concern is that HR will come up with the suggestion that I should work x months as (unpaid) intern or something. I don't know whether this is going to happen or not but I would like to be prepared if it becomes a topic, so...
Question: How do I argue in a professional manner that I am not going to work for free ?
More Context: I will apply for a paid position, however I think they might ask me to do a certain period as unpaid intern before giving me the job. Therefore my question: I don't want to work for free at all but how should I react when they ask me to do so even though I will have applied for the paid position?
The company might try this move simply to not heaving to pay me during that time. Something I can understand.
