For contractors interview is quit easy. In data structure they asked array and string and some technical question.and there were 3 round aptitude, technical and manager round. the level of aptitude question was easy to moderate.

Round 1 - Technical Interview. It was supposed to be Java questions, but interviewer was focusing on SQL. Questions were relatively theory based not related to practical real-world scenario. Looks like interviewer came here to humiliate and show case his theoretical bookish knowledge
