So interviewing is kinda the worst thing ever. You get nervous, you feel like you can't be yourself, and it's just scary. Here are my suggestions to make you look and feel prepared.
1. Use antiperspirant.
I suggest using CertainDri every night for a few nights before your interview. Use it on your pits and hands. Even if you never sweat, being nervous at your interview is normal, so it's a good idea to be safe than well...clammy.
2. If you're a lady with large boobs, use powder under your boobs.
I recently purchased the Silky Underwear Dusting Powder by Lush. It was only $7.95 and it was such a great idea. It has a light jasmine scent that keeps me from needing to use a strong fragrance. Typically, at an interview you don't want to smell like anything, but this is light enough to make you smell delicioso. Also, if your boobs are out of control like mine, it will keep your boobs from getting moist and won't shift your bra around.
