I used to get really nervous during interviews too, but I eventually found a few things that helped. First, I would try to do as much research as possible on the company and the position I was interviewing for. This helped me to feel more confident and prepared. Second, I would practice my answers to common interview questions out loud. This helped me to get my thoughts out in a clear and concise way. Finally, I would try to relax and focus on the conversation. I would remind myself that the hiring manager was just a person, and that they were just trying to get to know me better.
