One HR interview, one interview with HR and a company leader, two skills assessements, a personality assessment and one company-wide presentation. Weirdly, I didn't interview with the person who would be considered a manager of this position (They describe their company as flat. It's a little flat, but not truly). I think that was a problem because the process was effortful and it turns out I didn't have the basic skills they wanted. A better interview process would have caught that in the first or second round.
