I was a frequent customer in my local ULTA, and I knew several of the employees there. An assistant manager mentioned to me that they were hiring, and that I should apply. I was told to submit an application online, which I did, and I received a call a few days later. A few days after that, I completed an in-store 1 on 1 interview, and was offered a position by the end of the interview. The whole process took about a week.
The interview itself was very easy and very laidback. I had previously interviewed at Finish Line, Olive Garden, Ryan's Buffet, Victoria's Secret, and Applebee's, and this interview was by far the easiest. It took around 15 minutes, much of which was discussing the job responsibilities, ULTA's background and goals, and friendly small talk. The GM who did the interview did comment that the interview was short because I was a regular customer and was familiar with the store and company, and that it's usually longer for people who seldom or never shop at ULTA.
The interview questions were very basic, things like "Tell me about yourself", "Why did you leave your last job", "Why do you want to work at ULTA", "What do you like to do in your spare time", "What is your favorite cosmetic brand", and "Tell me about a time when you had to provide service to an unhappy or angry customer". There were no difficult questions, they were all very straight-forward and simple.
It helps to wear black to the interview, because the employee dress code is all black (with some white allowed), and it will help you look like you belong at ULTA. Also, if you are female, make sure your makeup is done nicely. Throwing in background knowledge about popular brands that they carry helps as well, as it shows you're well informed about what they have to offer. I mentioned that Urban Decay was my favorite brand, and that I frequently use their Naked eye shadow palettes, and the GM and I got into a brief discussion during the interview about our favorite shades on the palettes. Helps get you brownie points if you really know your makeup and brands.
Overall, the interview was much shorter and easier than I expected, and I was offered $1.25 more per hour than what I had asked for.
