Cummins Management interview questions

Had demotivating interview experience. Panel selected IT profile and it seems there were expecting mfg project experience. Worst thing is that, ladies of the panel looked frustrated and as if they already rejected the candidate. They were making faces as I started answering , their unprofessional body language made me uncomfortable. Also questions were not very much aligned, they were digging into my entry level experience and were checking authenticity. I am already having experience from big organisations but the way they treated me, I felt demotivated for next few days. They can reject the candidate but there should not be disrespect.
