http://www.theseblogs.com/CS5M7

U can refer VERBAL AND NON-VERBAL REASONING book by R.S. AGARWAL.. It is more
than enough.. also no need to do everthing in that book.. just do these topics
1. PUZZLES,
2. DATA SUFFICENCY,
3. PICTURES SERIES COMPLETION/OR SELECTING ODD PICTURE OUT OF 5
4. SYLLOGISMS (V.EASY..IT SAVED ME)
We had 5 sections each with 5 divisions
1) Had 1 Puzzle based on direction sense.. was easy but lenghty, so i attempted at the end.
it had 5 sub divisions
Something like..
P, Q, R and S are standing at the 4 corners of a square..n/w, n/e, s/w n s/e respectively..
N something like.. If P and R move one and a half distance in the clockwise direction.. Q
and S one n a half in the anticlockwise direction then in which direction is P with respect to
S.. something like tat
All the sub questions were based on the similar pattern
2) Figure Completion..v simple… people may think how it can be so easy, and they tend to
find something complicated in that but the fact is it is v simple
5 figures in a series were given n we had to find the ODD figure.. five same kind of
questions..
like out of five geometrical shapes 4 were divided into 4 equal parts, but one of them was
having 5 parts..thats it
also like a rectangle shifting by angle 45 in a circle in every figure.. but there was a tiny
circle besides that rectangle(ppl may think it is a printing mistake,and dont give it
importance), but tht tiny circle was missing in one of the diagram.. so tht was odd figure..
similar kind of silly questions were there.
3) Data Sufficiency… easy
A question was given followed by 2 statements We had to mark
1) If the first statement alone was enough to answer the question
2) If the second statement alone was enough to answer the question
3) If the both the statements were required to answer the question
4) If the question cld not be answered using both the statements
5) If either statement alone was sufficient to answer the question
A little practice (specially in problems related to maths equations, ages, relations,
comparison) from RS Aggarwal Verbal n Non Verbal will help u alot. 5 such questions were
given
4) Another Puzzle kind of question.. it was damn easy.. it was like
MR.natwarlal, a thief, steals only on the first day of every month of first quarter of year
(that means on 1st jan, 1st feb, 1st march).. this time he wanted a computer,So he steals
different parts from different persons.
but he has only 3 tools to use like a screwdriver, wirecutter, knife AND uses them only
once. he steals monitor keyboard and printer..in jan he steals monitor from A, but do not
uses the wirecutter.. next month he uses KNIFE to steal printer..and march was unlucky for
C..
and questions were like
1.Which tool he uses for stealing monitor.(ans: screwdriver)
2.which component was stolen from C (ans:keybboard)
3.which month was unlucky for B( ans:feb, as A, C were robbed in jan and march)
(REST TWO i dont remember)
5) Syllogism
In this section abt 4 statements were given in each questions (like all,some,not)
It was more like..

JUST REFER THESE TYPES OF QUESTIONS IN RS AGARWAL,(VERBAL NON VERBAL ONE)in
logical part first chapter, syllogisms
STEP 4: VERBAL
40 Questions
30 Mins
You get 2 comprehensions both were quite simple but do the comprehensions at the end..
Read the questions FIRST briefly.. then read the comprehension with proper concentration,
understanding each statement.. u can easily answer the questions 5 in each.. AS THEY are
lenghty attempt them at the end.. It will consume a lot of time..
10 Sentence Completions
4 statements almost the same but with some difference.. mark the one which is
grammatically correct.. look for spelling mistakes.. grammar errors etc..
5 questions based on choose the best option to replace the underlined part..
Simple paragraphs were given n questions were asked like which of these statements can
be inferred from the para, which is false according to the para etc..
5 small paragraphs and we have to choose what conclusion we can derive from them,4
options will be given and we have to choose the most suitable..
A PERSON WITH AVG. KNOWLEDGE OF ENGLISH GRAMMER CAN DO IT EASILY.. JUST
REFER YOUR ANY HIGH SCHOOL GRAMMER BOOK.
STEP 5: HR INTERVIEW
In the HR round u are basically asked abt ur self, ur r?sum?. There are no tech questions
asked n even if asked it will be very basic stuff.. They also ask puzzles..u need not solve
them.. they only look at ur approach..
The questions I was asked..
1) Tell me abt ur self
2) being an electronics student WHY u want job in software indusry
3) WHY I HAVE NOT DONE ANY PROJECT??????
4) and they asked abt my hobbies, my achievements, extra curricular activities (so mention
everything properly in ur resume,they will ask questions based on what all youu hav written
in ur resume)

http://www.theseblogs.com/CS5M7
http://www.theseblogs.com/CS5M7
http://www.theseblogs.com/CS5M7
They hardly eliminated people in the HR.. It is enough if u speak confidently.. yes B
confident, and dont try to bluff them.. and dont try to memorise any answer.. they will find
out.. even u have memorized, atleast pretend to think when u answer.
Getting thru Infy is not tough at all.. If ur good with ur Apti n have a good command over
English its enough..
All the Best..
