When you're ready to hire someone new for your team, it's important to think about what questions you should ask during the interview. You want to focus on the questions that are most relevant for your team and role you're hiring for, so you can understand how candidates will use their skills and experience to contribute to your company.

Look for someone with different areas of expertise from your own—this way, you can supercharge your team and get more done!
