I gave my resume first and i sat for sometime..Then i was asked to attend the Group Discussion.It was to check my communication skills.I easily got threw that round.After that i went for the aptitude test which was a challenging one for me. I got good marks in that also. Then the Hr people told me to go for a written test. I passed in that also. Finally i was taken to the HR round. Then I got the job and the offer letter. :)
