If you get the offer, just politely and graciously resign and thank them for the opportunity.
People do this more often than you might think. I used to hire many people and some leave right away and it's not hard to believe because you know timing-wise that they've been looking.
The compelling job offer had better be one that you plan to stay at for several years. You will burn a bridge with your current job.
