It was a very casual interview, where the focus of the interview seems to be about product knowledge and beauty industry knowledge. You need to really know what is beauty about and be prepared to share about your beauty routine, the brands you use, where you purchase your beauty products etc.
Apart from these beauty specific questions, the standard questions, strengths, weaknesses etc were asked as well.
Be passionate about beauty or I do not recommend this job because you will fall short during the interview. It is very obvious.
