PAPER : IBM INTERVIEW PAPER 21 NOV 2008 – CHENNAI

1) WRITTEN TEST:

a) 3 Matrices will be given each has 5 qns totally 15 qns and time limt:13 mins for tis section (no –ve marking for tis section-so attend all must k)

b) Number series completion total 20 qns time limit:4 mins for tis section (-ve marking of 0.25 is present) as the time is limited on cing the qns answer it else skip and forward BUT TIS IS DAMN EASY I attended 16/20 in tis section very easy

c) Aptitude totally 12 qns and time limit is:15 mins (-ve marking of .25 is there) (qns were from profit and loss, area, percentage, time and distance, age problems and etc but no qns similar to R.S.Aggarwal but similar to tat k so prepare well)

ONE ADVANTAGE NO SECTIONAL CUT OFF HERE. IN TOTAL ONLY THEY CHECK THE RESULT.. GALS NEVER MIND SINCE IF THEY R THRO IN WRITTEN THEY R INTO IBM BUT BOYS MAN OPEN UR MOUTH ELSE PROBLEM ONLY FOR MALE CANDIDATES GUYS..

MATRICES:

1) CLMN1 CLMN 2 CLMN3 CLMN4 CLMN5

ROW 1 J J U V X

ROW 2 U V J 5 6

ROW 3 V U J X 5

ROW 4 5 6 V J U

ROW 5 6 5 X U V

a) which has many maximum number of J s present in the following pairs:

i) row1 and column 1 ii)row2 and column 2 iii)row3 and column3 iv)row4 and column4 v)row5 column5

b) if all j’s are replaced by 3 and u’s replaced by 4 which row or column has d maximum value of 18

c)if all rows and columns are reversed and the diagonal from left bottom to right top corner has been reversed so wats the value in row4 column2

etc many guys cant remember to correct figures since I was in a hurry for answers so cant recollect the questions

NUMBER SERIES COMPLETION: (easiest of all)

And etc many it goes on totally 20 qns its damn easy just get the answer on first sight else forward to next qns…

APTITUDE: (a bit tougher tan other sections)

1) if a printer A prints 60 words per minute and printer b prints 80 words in one minute printer A starts at 7.47 and printer b at 8.07 wen ll printer b catch up wit printer A….?

2) a fountain is of length 144cms ten width of 288 cms and depth of 91 cms so how much litres of water ll be there in 46 cms of depth in the same fountain….?

3) there is a printer consisting of color and balck white printer the rate of color toner increases from $33 to $35 and black white toner from $28 to $29 if the total rate is $1600 there is 3/5 color toners wats d hike in price…..?

tats it I can remember friends….

FIRST ROUND STARTED AT 10.30 AND RESULTS WERE ANNOUNCED AT 1.30 AND GD STARTED BY 2PM

2) GROUP DISCUSSION:

Totally out of 500 attended only 30 were short listed for GD and 10 in each batch so from GD 28 of them advanced to next round.
