Trigent Software L1 Technical Support interview questions

She(HR) had asked to introduce then after that she told its customer support not technical, when asked why she told i was not good enough and she had doubt that I wouldn't clear the computerized accent round, later i told i have cleared it in amazon and Deloitte, i know im fit for that. She then needed a reason to tell, finally she told if i myself attend i doubt i would clear it. Thats not the way to answer, if she can't clear it why can't i ? That answer was ridiculous and i just came out saying I won't come if its customer support, ur not judging in the right way.
