Well...i dont agree wid u much..let me tell u abt my GD experience..it was on 27th march, 01.30pm slot,batch 29..my MP was gud, i got the first topic(academic dishonesty...) luckily...
let's come to GD, the main part...
I haven't started nd i havent concluded nd ofcourse, i hvnt got enuf chance evn to speak...!it was like full of fish market..four gus were fighting with each other..i managed to grab chance twice nd i added only two points(one point each time)..that's all...i was bit sceptic whether i will be selected r not..nd guys guess wt..i am the only one got selected out of the whole group(i verified the other guys number series wn they called for PI)...nd one more thing...i am not a christian..
so, this clearly states that.they wont consider, hw much u spoke..they juz consider hw many valid points u spoke..(no offence) nd one more thing, i dnt think they gv more(may be little) preference to chiristians(it is not mentioned anywhere in their website)..bocz i met something around 50 to 60 guys thru diffrent communites (orkut, fb etc..,) who got selected in christ..out of those max. r non-chirstians..
so, nw its up to u to find out that where it went wrong....!
P.S:- I hv mentioned my exp. juz bcoz to advice PUYS to not get carried away with the rumours..but not to offend anyone..
