I would do something like Illamasqua Purity or Nomad, or Nails Inc Baker St.. It shows that you know nail stuff (and used a brand they carry), is a bit trendy, but not too over the top.
I advise you to do classic french manicure:P you can add also glitter line or some rhinetones if you want:P However, I will do white french tips ....;:P
Won't a beauty shop appreciate something unique and interesting on your nails?
Hmm... looking through your archives, how about the Barielle Gold Digger? It's pretty and classy but not boring.
I would chose a polish you love and has a great formula to get a nice finish with out having to fuss with it - I'd avoid anything that chips easily or clashes with what you are wearing. I think a deep blue cream would be pretty - not super conservative but not distracting. Good luck on the interview!!
I think pastel or nude colours would be suitable! :)
I honestly would do a subtle gradient on my nails, just to show them what you are capable of without going overboard!
I always wear OPI Tickle My France-y to interviews :D It's my lucky color.However, since it is at Sephora, a little bit of creativity wouldn't hurt. Maybe a sponge manicure, but keep the shades neutral and not too contrasty.
I say short, squoval nails with a medium-dark blue or grey, or black. Goes with their trendy atmosphere.
And good luck on your interview!! :)
I'm late on seeing this so how was your interview?
