If you have engaged with me in bad faith (pretending to want a job with us when you actually don't) then I would be very uncomfortable endorsing you to join one of my teams in the future.
By all means, interview around. And if you get a better offer and accept it, then I will cheerfully congratulate you and wish you the very best of luck! But if you're operating in an area where the pool of potential employers is small, make sure you don't burn too many relationships in the process.
