['I had my first professional interview recently!', 'congrats, how did you handle the pressure?', "Pretty well I think! I had a solid resume, and I practiced ahead of time. It still isn't the same though when you're right there in the room and they're looking at you lol."]
It can be pretty nerve racking, but it is always great practice. You will only get better.
When I went in for my first professional interview, I was ready for anything. I practiced interview questions, had a great resume, and a pretty snazzy outfit.
