It was a very informal process for me. Happened simultaneously when I submitted my job application which was very straightforward and quick to fill out. The interview itself simply asked about who I was really and what my plans in life were. Then, because I was applying for a seasonal job, I was just asked for my availability throughout the season and whether I was flexible for certain times. I honestly didn't even know I was being interviewed until after I was accepted into the job!

Pretty short and straight to the point. Ask you basic scenarios, past work experiences, all that good stuff. They also ask technical questions like are you a us citizen and what not. But overall super easy.
