How do I make sure I am asking the right questions?

You don't need to invent clever questions or ask the candidate for examples of the experience you want to hear about. Asking "Tell me about a time when you…" tells the candidate the answer you want. Instead:

1. Start from the Cipher. The Cipher says what success looks like in the role. Every question exists to collect evidence against it. See What is a Cipher?
2. Use the same template for every candidate. The standard HireBest decision interview asks the same fifteen questions about each chapter of the candidate's career. Any difference in what you learn then comes from the candidate, not from you.
3. Ask unaided, open-ended questions. Ask for the top three accomplishments, not for a story about the skill you hope to hear. Then listen for whether the answers match what the Cipher needs.
4. Drive to specifics. Follow up until you know what the candidate did, what went well and what did not. See What's the best way to ask the questions?
5. Get an answer every time. If the candidate sidesteps a question, ask again or use the question's prompts. See What is a question prompt?
