Bluemercury Retail Sales Associate interview questions

They reached out to me after finding my resume online and invited me to interview. Once I'm at the store I realize there's a few girls showing up after me. No biggie... until it's been about 30 minutes I've been waiting for my interview. After 45 minutes of waiting the manager came out, introduced herself to me and then told the girl next to me "It'll be 10 minutes" WHAT? I waited this long to interview for 10 minutes? So I wished the company good luck and declined. Horrible attitude and very unprofessional.
