Obviously, depending on what your specific needs and concerns are, you'll need to tailor your questions to that situation.
But, in my experience interviewing candidates for different types of jobs, I've learned there are a number of questions that are much more effective in assessing candidates for a given role:
- For any job requiring initiative, I ask the candidate to tell me about something they get passionate about outside of work. (If you can't get passionate about something you love at home, you won't likely muster it at work).
- For any job requiring self-organization, I ask candidates for examples of things they've done in the past to stay organized.
- If I care about how much someone will prepare for a given work situation, I ask them their strengths and weaknesses (which are crap ways to learn someone's strengths and weaknesses, but anyone without a well-thought out answer has done roughly nothing to prepare for typical interview questions).
- When you're considering a surgeon to work on you, the key question is generally believed to be "how many times have you done this specific procedure?"
Etc.
What are the key questions that one should ask a nanny or full-time babysitter?
