I've been working as a contractor (through an agency) for a software company for a few months now. Recently, the higher-ups approached me and said that they liked the work I've been doing and asked if I would someday consider being hired as a permanent employee.
I'm not particularly interested in doing so - I like the company, but the primary reason I was looking for a contracting position was to hold me over after graduating from university because I don't want to get tied down in this area. My contract is not a fixed duration so I figure I'll wrap up when the projects I'm working on are finished, which currently looks like 3-4 months from now.
How do I graciously say "I appreciate the offer, but I'm just interested finishing the projects I was hired for?"
