The interview process can stretch up till an eternity, plus you will never know that you have been rejected and the reason why, HRs won't respond to your e-mail.

I applied via off-campus recruitment, called for in-office interview, all applicants had a pen-paper test, followed by 2-3 technical rounds and then a HR round. All rounds were elimination.

The topics covered included level order binary tree traversal, reversing a linked list, finding the middle element of a linked list, basic OOPs concepts, printing all leaf nodes and their parents only from a binary tree, and a few puzzles.

The second last round was with the Director who in the end asked me for 'my full name' (indirectly he wanted to know the caste to which I belong) despite having my resume in front of him.
