I applied online. The process took 4 days. I interviewed at Brilliant Earth in Aug 2014
Interview
Lasted about twenty five minutes. The questions asked were similar to what others had described. You're expected to do research about the company through their website beforehand. I was given scenarios on what to do if jewelry was missing and where to look for it first. Pretty much went through what others had described on their own interview process.
Interview questions [1]
Question 1
The sales tax question was difficult but expected since others over here have mentioned it before. The math part is easy, describing the process is difficult since you don't verbally describe a math solution on a daily basis.
