I do not think the role was actually open to the general public. I think they needed to meet a quota for external outreach. So they posted it on LinkedIn and other career sites.

The interview consisted of conversation with team members the position would interact with, including the hiring manager and upper management representation. Everyone was very friendly and easy to talk with. Coordination of the entire process went through HR. They were very helpful and informative all along the way. The one-on-one interviews were short and to the point.
