I never smoke, but over 2 weeks ago puffed a few cigar puffs to try one. didn't inhale. will it show up in hair/nicotine testing for preemployment?

No: If you didn't inhale, there will be no nicotine to detect.

Yes: Nicotine hair tests can detect smoking for at least 90 days and possibly longer. You don't need to inhale cigars (in fact most people can't) to get a significant dose of nicotine. Just puffing is what most cigar smokers do and they get plenty of nicotine. Not inhaling only works if you are bill clinton.
