Preparation for interviews??


I got a GD/PI call from MDI, Gurgaon for their PGPM course. the problem is how do u prepare for an interview? i can still understand preparing for gd..but how the hell do u prepare for an interview? to get the answer to this question i joined a coaching institute. after the whole thing got over i understood just one thing. they just confuse u,thats all. some ppl will tell u one thing,the others will tell u something totally different.
sample this:
question:wat will u do if u do not get selected to this institute?
orientation session 1:
sir i will work for 3 yrs,weigh my options n then think bout wat i need to do.
orientation session 2:
sir i will go home,think bout wat went wrong.i will work for a year,n come back again.

hmmm now i think if im honest they will chuck me out..quite frankly if i was the interviewer,i would chuck myself out.so though the second orientation thing is wat i subscribe with,i decided to give the first one a try at a mock interview.
i got shredded to pieces there..the interviewer told me "that means u r not dedicated towards doing an mba.ur just here because u have the opportunity.u said the earlier the better,then y wait for 3 yrs?"
i think im going to be honest on this one at least..i will go with the second answer..

these mock sessions came with their share of entertainment too..i spoke to an interviewer who told me that ppl came in who were hilarious..the interviewer asked one guy "tell me something bout delhi"..so the guy replies(keep in mind he must be at least 20) "delhi is the capital of india.delhi is having problems of terrorism." that has to make the interviewer go nuts..

conclusion i reached:No matter wat u say,u can be shredded to pieces.the interviewer is like god.
watever u say will be used against u.
