Like most, everyone said it all depends on the type of job you are interviewing for. If it was for a law enforcement or firefighter position then pants are necessary. However, it depends on the job you are interviewing for, but I think the kilt would divert the interviewers attention away from your face to your kilt, hose, flashes, and possibly your Sgian Dubh.

You never want to wear loud ties or too many lapel pins, carnations in the lapel either, because the person on the interview panel may be allergic to flowers, the lapel pin may be offensive or a detractor to the panel of interviews etc... Blending in and presenting a professional appearance is your best bet and to me that means wearing a good suit and tie, let your resume and answers determine weather you get hired not your choice of attire.

Good Luck as I am in the same boat.
