I applied through my University recruiting website. I created a cover letter video to attempt to stand out, and that seemed to work for me. I was then directed to complete an online video interview of 8 rapidfire questions (you get 30 seconds to think and about 1 minute to answer. Then it saves and submits your video). You have to be ready for any question here, things like "If you were stranded on an island and had only 2 things, what would they be?" Also, there is an online case through the website "Mindsumo" that accompanies the hiring process. It will be specific to your position.
From there I was informed that I had received a final interview and they flew me out to Las Vegas. For two days, I met the team that you are applying to be a part of, and I got to know other company members and the Zappos campus. There is a "Culture interview" and a more professional, "position specific interview." I feel like both went very well, the culture interview had some unique personality questions like "if you could be doing anything in the world and money didn't matter, what would it be?"
No offer, but great experience. I knew it was going to be a different interview based on the culture, so I was prepared but it just didn't work out.
