I applied and gave interview 3 times. First two during campus and last one through placement agency. When the number of attendees are large they filter by asking you to pronounce words. Or may take a small personal interview about yourself and so on. If you pass through that then comes worst part. Around 2-3 rounds of telephonic interview. Now if all attendee are freshers you might be selected out of pure luck or you might have just impressed them by your non stop talking skills as though you own the world. Yes right the main they look forward is confidence in your comnunication. Even if you hesitate make sure you don't lose confidence. I didnt get through because even though i was confident i wasn't much of talkative. I was at loss of words with nervousness.
