⟩ Explain me have you ever had a side hustle? If yes, what is it and why did you start it? What results did you see from your efforts?
You can tell someone is a true hustler if they're working on a passion project outside of work. You do of course run the risk that they'll eventually leave to pursue the project full time, but you'll know that they're driven, well organized, and fully able to build something from the ground up.
