Domande di colloquio per Senior Java Developer presso Cardinal Technology Solutions

My interview has been taken by 3 persons, one by one. First 2 round interview was done well. Third round interview taken by team lead. But he start asking me the questions in the area which I do not mentioned in my CV. I don't know when I have not mentioned in my CV then why he is asking such a questions? Its look like that he already decided that not to recruite me. He is in negative mind set I don't know why. Environment of the company looks good as per the body language of the team lead because he is very affraid about his job security. I thought he think thathe might be face some questions if he selected me and if any issue occured in future so that he already mind makup that he will not recruit me and thats why he stary asking me in the area which are not mentioned in my CV.
