It’s totally natural! As someone who has to conduct the interview nowadays, just know that I get nervous as well before going and conducting them, too.
As someone being interviewed, I found that for me really practicing my “script” helps calm the nerves. Interviewing is really just telling a series of scripted stories, so have several lined up and just practice telling them. Interview questions are incredibly repetitive - so you can really find the stories that try to highlight your strengths and then finding a time in the interview to deploy them.
Lastly, something that helps calm my nerves is really knowing that I have some power here, we both have the ability to say no to the opportunity. So, it’s a meeting to really determine if I have the skillset that’s desired by the company and if the fit is good for me as an individual. Remembering the power balance can give you a little bit of swagger back.
Best of luck, OP!!
Sounds like a lot of fun, thanks for the recommendation!
