it is a 2 stage process.ist round is written followed by personal interview.....

as i am from mechanical background so they donot go deep into the language part but simply asked about my favourite subject and started asking question on mom.ist que was to explain how deflection occur and the second was from bending moment.
during hr round the first question asked from me was how u spent your 24 hrs of the day?
then they asked abot my favourite song and actor.....

for getting into infy is very easy once you r through with your aptitude part the think that 95% you r selected.
for interview be bold and confident.you tone should be constant at particular pitch....

approx 500 students applied out of which 265 got selected finally....
i think good aptitude solving skill and communication skill was the key to my success.
