One time I went to an interview for a really competitive internship with a great company in my field. I thought it went great and that the interviewer and I had a great conversation, but it turned out I didn't get it. 
Yeah, those are rough when you are so hopeful about it.
Yeah it was really disappointing! 
Yeah, hopefully your still looking for another internship.
Well actually I did get another one! So it worked out, I think for the better actually.
