My favorite 2 interview questions are 1. "What is the hardest thing you've ever done?" The answer can be personal or professional. What the candidate accomplished isn't as important as how -- and why. What were the hurdles? What were the roadblocks? Did the candidate seek help? Does the candidate credit the people who helped? The answer also can provide insight into how the candidate defines "hard," and how their perspective align with the challenges your business faces. 2. "When have you experienced stellar customer service, and how did that change how you deal with customers?" This question is a great way to see how candidates define "stellar customer service" -- not just as they experience it, but also in the service they expect themselves to provide.
