Despite his delivery, I respect his interview question. How do you get people to work for you who don't directly report to you?
Small company. One of the directors created a new position and told me I was the sole candidate right now. I would be a "Project Manager" for software products. I had a meeting with the owner to discuss my contract and pay, etc. Then he told me that I couldn't be a project manager as I wouldn't have direct reports; they would all report to the director or he. He is concerned the idea is bound to fail without me having the "direct authority" to tell people what to do and when to do it. The company is so mall that there really aren't enough people to have some directly reporting to me without hiring. It would be a manager and her lone direct. "Project manager is a nebulous title that means almost nothing."
I was a little stunned by his suggestion to be honest. I'm pretty sure there's an entire book defining project management (PMBOK), and I've worked on a dozen teams where I was the project manager. I have worked with people who had other managers that filled out their review and paid their salary. In hindsight though I couldn't readily explain to this man why they "did anything" for me. There was a shared goal, and I didn't so much view the people as reporting to me or working for me. I viewed us a team trying to push the ball over the line.
