I hate panel interviews...and group interviews...yikes
I'm sorry you're feeling so nervous about it, you aren't alone. Presentations make tons of people anxious. I'm sure those panel interviewers are glad they're on the opposite side of the table not having to give the interview, it's always easier being the one who judges as opposed to the one who preforms. So just know that they usually have sympathy unless they're cold heartless people. Sometimes they will even help put you at ease by making the interview easier and less daunting.
