I got a very snarky email from their HR telling me my desired salary was out of the pay range they "had clearly posted in the job listing". I went back and carefully looked. There was no pay in the listing so they were wrong. Don't be rude to your applicants, especially when you're wrong.

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.
