Wait and see if you definitely have the job in the bag before you say ANYTHING to ANYONE.
If it turns out you have the job (offer in writing, etc), then get the wheels in motion to discuss leaving.
Besides, aren't you a contractor? I would think the rules don't really apply to you in this case.
And technically this is a new rule after you've already started interviewing.
Too bad, so sad for your current employer.
That's business, baby.
