 Regarding Hughes
 paper they conducted two tests. Both were technical(no aptitude test). First one was compulsory for everybody. In second one could opt for electronics or computers. In all i suppose there were 50 questions. I sent a request to my classmates to send me questions whatevery they could recall. Till now only one person has responded. I am sending those questions to you.

And just before interview you were supposed to fill up a performa which they call Behavioural Test. This was to check you interpersonal skills and socialising capabilities. Questions like - would you like to be elected leaders of organising committees, do you like peoply express their agonies to you, do you wish people be close to you type questions were repeated in one and the other form.

Interview was technical as well as personal. CGPA did count - it seems. They selected 8 people from here. BTW what s your current CGPA and what s the strength of your class. Do they come for B.Tech and M.Tech separatel as the case here is or it s all at once.
