IBM came here in BIT on 9th july..the questons where very easy ..there were only 40 questons to be done in 60 minutes .. so enoughtime ..right!!20 Aptitude and 20 technical( C , unix , sofwtare engg,computer n/w)

the questions which i rememeber are ..6 equal cubes set line by line there . and the perimeter of therectangle formedwas given.. and u have to find the area of eachsquare.

2.A man sells some item at some amount to which he losses 3 or 5 %(didn't remmeber much) u have to find to how much amount he shouldsell the item to gain the profit of 10%.4 or 5 logical questions.like in certain place there are two kind of official lives type Aand type B ,. type A says only yes while type B only says NO.... answer them carefully .rest of the questions where easy.

17. which among the devices is spooled device ans: printer(correct)

18. if u get error in adapter which device will u use? ans: contact electronics student. one of the option was voltometer.


9/22

thats it i remember

dont email me for further clarifications because i typed what all i know.

but one thingthey are changing papers but the quetions will be from previous quetionpapers combined.

i am in Computer Science Branchtake the advantage of branch for CS brach people.--------for girls just get 25 in written for 40. and talk something in tech and HR u will be in best opportunity for girls its like 50% reservation for girls.---------and the pay package is 2.75 lakh per annum.

the cut off is 30

final word: dont go blindly with this answers to exam conform all the answers and then share this paper with all of u'r friends. they(IBM) need people badly

so if all of u'r friends do well all of u will be in.

Interview:it depends upon the Panelbe perfect with u'r mini project.

HR quetions:1. why 2+2 is 4 why not 5.

ans: assume u took 2 apples from A and 2 more apples from B and assume u are having 5 and give 2 to X and give 2 more to Y then nothing will be with u i.e u

lossed. (give some answers but dont say that it is like that)2. why IBM

and etc .........
