Very casual. I applied online when a friend informed me that they were hiring. I arrived to speak with the manager, luckily there was a job fair (basically it was a group interview) set up that day and I hadn't missed it yet. The job fair consisted of introductions and two questions. 1. Which superhero would you be and why? 2. If you were offered an all expense paid vacation anywhere in the world, where would you go and why. Next, the two hiring departments chose who they wanted to interview individually. I was asked why I was applying for the position by one manager and why should they choose me by the other. I was hired.
