Indian Energy Exchange interview questions

My interview was schedule in month of August 2018, My 01st and 02nd round was very well taken and panel was too good i was very happy until i meet the senior person for final round of interview , i was very much surprise to see that attitude and the way of asking the question was very bad i mean he was too rude, as per my understanding he himself don't know the answer of the question what he is asking me, request to HR check once how the interview is taken by the interview panel, i thank to god that i got rejected i would never work with such type of the person who cant talk or don't have any knowledge of taking interview
