X-Rite Customer Service Representative interview questions

I felt very defensive in my interview with HR. Like I was a inconvience for her. 15 minutes and I was done. Had 2 other interviews right after HR's and felt for a call center enviorment that I was getting interrogiated. Never felt so uncomfortable in a job interview. I thought I was qualifed, however after leaving, it was obvious I wasn't going to make the cut.
