Had an interview today and i wanna die rn.

Had an interview today and i wanna die rn. Had an interview for a big firm today. Was really looking forward to having a good one and hoping my achievements and GPA will fill up the blocks of my speech. But i guess i was wrong to be optimistic for once. They were calling in 2 ppl at a time to the interview room. I went in with another guy and he was called to interview first. He had a pretty good and long interview. Interviewer asked him all kind of questions, related to our course, his final year project, other shit like how much salary are u expecting etc. His interview went on for a about a good 10 15 mins. I was sitting behind him rehearsing for those questions. When i was called up, he asked me to introduce myself. As soon as i started stuttering, i could see the annoyance on his face clearly. It was almost like he wanted to shout SHUT UP but couldn't. Not 10 seconds in, he told me (rudely) to write what i wanted to say. I was kinda relieved that i wouldn't have to speak for the rest of the interview. And as soon as i finished writing my intro. He told me that my interview is over and they'd call me if I'm selected(like thats gonna happen). Its been hours and i cant fuckin get this out of my mind. All my achievements and GPA doesn't matter coz i can't fuckin sell myself in an interview. FML.
