Started with a phone screen with an HR rep. Then moved on to an in-person interview with an employee of a different team, but had been at the org the longest (3 years). Was sent a homework assignment which consisted of "In a 1-2 page memo to the VP of Programs, please articulate the process you would recommend for leading this initiative. Additionally, please include a draft timeline that highlights key milestones for the project." After that was invited back to meet with hiring manager, and the person who oversaw the whole department. Shortly after was contacted by the HR rep letting me know they had chosen someone else.
In general, it was a quick process. The HR rep was not always responsive, but I found out later was an external contractor which could have accounted for the delays. The folks I met with were clear about expectations for the role and the type of employee they were looking for.
