IN WRITTEN TEST: THERE were 3 sections;

1st section: IQ test ; in this there was 36 questions ;TIME:40 min; It comrises only figurative type like series pattern Two rows r given of figures each of 4 fig, and the third row consist of 3 fig and 1 blank which u have to fill;These u can got from R.S AGGARWAL VERBAL AND NON VERBAL REASONING...

2nd section: consist of aptitude in which no. of questions =60 and time=40 min..this paper was really interesting and some what difficult all teh 40 qns was of figurartive type but different from IQ; like 4 fif r given of ships and forces r applied to it at different positions and u have to find which will be align in some particular wind direction..or forces applued on a string passing trough different pulleys r given and which eill be have fastest speed or max displacement..max questions r of GEar type different gears were given and 1 direction is given & u have to find the direction fo some ther pulleys\'s directions..

There were 10 reading comprehension, 10 fill in the blanks, 10 logical questions including coding.
e.g.

Some questions were like:
There are four sets of questions each consists of three sentences.
Indicate the set(s) in which the last sentence logically completes the previous two:
The sets were like:
All farmers are poor. He is poor. He is farmer.
All cats are dogs. Few dogs are foxes. Few cats are foxes.
Some cashews are peanuts. All peanuts are walnuts. Some cashews are walnuts.
All dogs bark. The man is barking. He is a dog.
Some honey is sugar. Some bees are sugar. So all bees are honey.
All hats are red. Roses are red. All roses are hats.
Coding example:
(1) MONKEY => JLKHBV - go 3 letters back in the alphabet
(2) DIG => AFD - the same as above and a few more....
