First I think you need to decide just how much you want/need this position. Second, I think you also need to understand if kilt wearing on the job is a deal maker or deal breaker for you. Wearing a kilt will certainly leave an impression - now just what that means depends on you - and the folks that interview you. Interviews are interesting event. Assume that everyone who makes it to the Q&A stage has roughly the same skills and abilities - at this point the chief and others are trying to decide if you will "fit" in the department and of course you are trying to decide exactly the same thing.

There are lots of books and websites that will give you tips and offer you techiniques for successful interviewing. My personal opinion is that after you get past the "stand tall, walk straight, and look people in the eye" part, lots of the rest is about gamesmanship in the interview process. My advice is... be yourself. After all that's all you really can be.

You may have noticed I haven't given you an opinion on wearing a kilt. Afterall, you are the only person in the world that can really make that decision. I will give you one small suggestion... to thine own self be true.

Good Luck no matter what you decide!
