@JezzIt,
I just started at Sephora, and I know a color lead is responsible for basically being the go-to person when it comes to anything "makeup" in the store. At our store we have a color lead, a skincare lead, fragrance lead, operations lead etc. We also have what you call a "Beauty Studio Captain" who is in charge of actually applying makeup for our clients at the beauty studio. If you don't know what the beauty studio is, it is basically the big vanity in the middle of the store where you can get your makeup done. We have an express makeup application which is a basic makeup application to either your skin, eyes, lips etc. and we also have a full on makeup application where you have to purchase a minimum amount of products from the store.
So you are basically manager when it come the world of color at Sephora. I believe you have be knowledgeable about our makeup products so you can help out and sell makeup products to client, fill them in with knowledge about makeup products. Also, you're responsible for sharing your knowledge for your fellow sephora team mates. You wanna serve as a mentor to those who wish to be in color as well
I'm not one hundred percent about the actual job description, but in your interview make sure you fill them in about your knowledge about products that sephora carries, and also how you also want to gain more knowledge as well and learn from other leads. Also make sure to let them know you want to inspire others when it comes to color; clients AND other cast members. You wanna be their leader, their mentor, and be able to answer any of their questions. Working at Sephora, I've learned that the company is very team oriented and we value teamwork and using teamwork to serve our clientele. So show them that you are a team player, but at the same time show them how you can be a great leader.
Thats pretty much all I have for now, I hope it helps. If you have further questions, ask away
