Google Engineering Manager interview questions

Started very reasonably with talk about team leadership, people management, systems and architecture. Then it went onto coding/algorithmic exercise in a google doc blank page. This was odd for a managerial position.

First call with coordinator. I was prepared for onsite interview and was told about what to expect. Then an on-site interview consisting of two system design interviews, one coding, a people management and a technical leadership interview. Exactly one week later, I was notified of the decision.
