Started with a phone interview, with the person I'd be working with. Simple questions about job history, and example of what I'm working on currently. An in-person interview was then scheduled, though the person who hired me said at the start that they wanted to hire me already and the in-person part was a formality at that point. They wanted me to start quickly, though I didn't need to give a two-week notice at my then-current employer, because my boss there was headed out of the country for a month.
