There were 3 rounds one online test and 2 technical rounds. first was online test based on oops concepts and 2 medium difficulty coding questions. Second was F2F technical round in which a coding questions was given to implement oops concepts and linkedlist implementation. Third round was F2F round with 3 members in which java based questions like interface, immutable class etc was asked along with one logical coding question. Got rejected after this round so idea about futher rounds
