Infosys Dot NET Developer interview questions

I had selected through their Career website in bulk hiring recently. My interview was scheduled on Saturday and I joined it , the interviewer told me to wait 2-3 minutes to start. I think that is someone else is joining to examine my technical skills (interviewer seems to be hr or someone else department) but after 4-5 minutes he told me to start. He didn't ask anything technical relevant to the role and asking questions on my current project domain in my current organization...what is this dude Even though I explained everything to him properly since he didn't have the knowledge about that domain and after 25 minutes he said ... He is done and within 1 hour after interview he updated my status as rejected at interview... I was like man you didn't asked anything relevant and what I explained you were unaware.
