job interview

 went to the interview today and it was a group interview..and in my mind I was thinking it would be a group of them asking me questions and what not...but no...it was a group of interviews and a group of them..and we were all interviewed at the same time....and I really truly don't know if I did good or not once I figured out wewould all be in there together..i tried to hold it together and be present and make eye contact and answer... the questions...but at the same time I kept comparing my answers to there..was I wrong ? did I leave something out? I should have said something else ... im so frustrated because I really cant tell..there was a written part too and I think I did ok on that..but there were 7 of us interviewing for 2 positions....im trying so hard to be positive..but im scared I messed up..
