Note - I had answered all the questions and almost all were correct, still not got shortlisted for 2nd round, All CS & IT students were eliminated from round 1, and only electronics students were selected in the end. The same had happened last year.
Tip - Please don't rely on one company , may companies do like this that they will select students from that particular branch even though you may have given good interview.
