Everyone gets nervous, it isn’t a big deal. Roll with it and remember, you’re just talking about yourself, and meeting a few new people who want to hear about you. Save the nervousness for things that really require it.
Within your answers tell them WHY you do what you do. Tell them what in your life motivates you. And tell them why you would be an asset for THEM.
Best of luck, @legowarrior, nail it!
