Eastman Chemical Engineer Co-Op interview questions

I was interviewing at my university coop day. i had done hours of research on the company and prepared answers to STAR questions, The interviewer was an older gentleman and when the interview started he asked if I wanted to know some history about Eastman. I could recite the history of Eastman but said yes out of politeness. BIG MISTAKE. The guy rambles on about Eastman and all their product lines since 1960. After 15 minutes I prompt him to ask me questions, we run out of time, in the last 5 minutes of the interview we are flying through STAR questions. What really irritates me is that I know both of the 2 students who got the position that semester. They had fewer credit hours, lower GPAs, and comparable extra curriculars. The only reason I can think for them getting the job over me is that I absolutely shanked the Interview.
