They call it a "Structured Interview." It's a series of extremely general questions asked via phone interview with a four-person panel. The questions were extremely general in nature and terribly difficult to answer to their apparent satisfaction.

Four rounds: phone, Zoom, in-person group, then a series of one-on-one interviews. Smart folks with good questions. They fed me lunch, which I liked.

Applied in response to Expression of Interest. Weeks or months later you hear back and get an interview, but you aren't told which project it's for or what skillsets are necessary. Weeks or months go by, and you get an interview with a project team.
