I guess Interviewer was thinking himself too smart. Asked me to develop spring boot app and then spring related questions, It was easy. Although, he wasted my time for 1:35 hrs beacuse I get rejection mail. He told me like for couple of month people have to work as a tester here, If I am comfortable with this or not, I mean if I am interviewing for dev role Why I would be comfortable for testing role? He told me that one employee is irritating them as she is asking to change her role. If he is so irritated and if this is so normal there then he should change his role.
