That was the system we had at Nest. We called it the Three Crowns. Here’s how it worked: Crown 1 was the hiring manager. They got the role approved and found the candidates. Crowns 2 and 3 were managers of the candidate’s internal customers. They picked one or two people from their team to interview the candidate. Feedback was collected, shared, and discussed, then the Three Crowns met to decide who to hire.
