Exam Pattern ::

2>Technical Test
3>HR Test

1-APTITUDE TEST
My aptitude test was online. There is no need to panic, its very simple. There was no sectional cut off & no negative marking. Time was fixed for particular section, once the time for one section is over u can not return back to it or change the answers for that section's can change the answers in a particular section in the time limit provided for that section, for example u can change the answers of English section in the time provided, first 20 minutes but after that u can not, as after that quantitative section will come automatically.

It has 3 sections:-
1>English -(time-20 minutes)-(10 synonyms + 10 antonyms + 8 fill in the blanks + 1 passage)
2>Quantitative -(time-40 minutes)-(38 questions)
3>Critical Reasoning -(30 minutes)-(3 reasoning passage)

1> ENGLISH
In case of English, the paper was very very standard. Most of the antonyms & synonyms were really new, I mugged many but it didn't helped me allot, but I will also suggest that go through different paper like mine one. U have to use ur IQ to solve most of them, I will suggest don't waste extra energy on mugging up anto. & syno., but ya mug up the common ones.

# Synonyms & synonyms:-
Most of the words were new, so I don't remember, but still what I remember I will write, do both antonym & synonym of the word ...

# fill in the blanks It was really tough, I really don't remember, but don't worry much as there r many set of paper, u may get a easy one, as told by friends that few of them got easy ones.

It was a psychological type passage, (but NOT psychological paper) I read all the passage of Barron but it was not from that, so b prepared.

Ans:12:00pm

Don't worry for N,S.E & W  it does not matters .

1o change == 4mins
Here 20 o+40 o=60 o
So 60*4=240 mins....4hrs
If time change not considered, then after 10 hrs it will reach at the same palce after 6:00+10:00=4:00pm
