Cognizant Placement Paper Set 2

Written test consists of three sections

VERBAL SECTION (25 questions-25min)

(1-10) comprehension (passages r too long)
(11-15) find the incorrect sentences
(16-20) find the correct sentences
(21-25) arrange the jumbled sentences
This is a quiet tough section. Just make guesses. Mark option B or C.Always read passage at last.Read questions first.
ANALTICAL SECTION (25 questions-30min) 
(1-5) Venn diagram 

A group is divided into three. The first group is persons of 5'6 height and second and third r 6'0 and 6'6 respectively. There r totally 130 peoples, 50 of them r 5'6 and 65 of them r 6'6, 10 of them r 5'6 and 6'6, 15 of them r 5'6 and 6, 20 of them r 6'6 and 6, and 5 of them r all the three.
(1) How many of them r 6 feet? (Ans 70)
(2) How many of them r only 6 feet? (Ans 30)

Important formula in Venn diagram is
EXACTLY ONE = TOTAL - EXACTLY TWO - ALL THREE  
(6-10) quantitative questions  

Questions on Blood relations(quite difficult) 
Other questions r from profit loss and other general questions. Sorry I don’t remember  
(11-15) data sufficiency--Very easy one
(16-20) binary conversion
Please don’t read anything in the question. Just change any value to binary and convert that 1 to $ and 0 to *.
(Eg) LCM of (12 15 10) (ans 60 = 111100 = $$$$**)
(21-25) cubes
Questions like :if a dice is thrown 2 on top,3&5 at left &right,in another turn 5 on top,3&4 at left&right and one another condition(dont remember exactly)
21-25 What is opposite to 5?.....
NON VERBAL SECTION (20 questions-20 min)  
(1-4) syllogism (study all rules in the aggarwal book but TIME book will help u a lot)
(Eg) All mosquitoes’ are lizards.
All lizards are insects.
(Ans: all mosquitoes’ are insects)
(5-6) logical deduction (study all rules from TIME book)
(7-15) figure sequence and odd one out from figures (very easy)(just go through R S Agarwal)  
(16-17) Seating arrangement
(18-20) logical puzzle
After two hours the sortlist was declared by them .I was almost sure that I would be clearing the aptitude.

          
The Merit Track conducted the test. It was organized perfectly and they expect discipline from us.. Before the test u have to fill a form. Do it carefully because some of my friends got questions 4m tat.

1.Software Orientation:
2.Hobbies and extra-curricular activities
3.Strengths and Weakness
4.Expectation from CTS
5.Why CTS
6. Long term and short-term goal with CTS
7.What are the qualities necessary for software professional to be successful

WRITTEN TEST (3 sections) NO –VE MARKING

1.Analytical Ability (25 Q, 30 Minutes)
Venn diagram questions
Data sufficiency
coding 1 represented as $ and 0 as *(easy.. jus convert it into Binary)
Cubes related questions are very important

My suggestion is do Coding First. Then Venn dig. Cube problem n others..u can surely score full marks fm coding n venn dig…cube is also easy when u understand it.For cube take the cubic root of the no of pieces.64 means 4(keep as x value)..then 2 side painted means   12*(x-2).1side painted means 6*(x-2) 2 .  (horizontal n vertical) like wise u must think  n apply according to the question..

1.venn dig- people hving dif heights 6feet ,6’6 feet, 5’5 feet.and questions like no of people who is 6 feet.no of people who is 5’5feet…..
2.In codin there will be only normal arithmetic operations n L.c.m..i don remember them.
For ex..64/4= 16 = $****.first solve it n convert it to binary..

3.Cube- a cube of 12 cm is cut into small 3cm pieces..then place another 4 small cubes  over it..and another 2 small cubes over the 4cubes..then again one more cube over the 2 cube…the cube is then painted from top to bottom
12/3=4…so 4row 4column…draw a dig of cube first. Imagining the cube only help u to solve rather than formulas. How many cubes r painted on only one side?
how many cubes r painted on only 2 sides?
how many cubes r painted on only 3 sides?
how many cubes r painted on only 4 sides?
how many cubes r painted 0 sides?
(my friends told me tat cube problems hav more marks than other questions)

2.Verbal Ability (20 Q, 20 Min)
Comprehension
Find out the incorrect sentence
Find out the correct sentence
Jumbled Passages
-Don prepare any thing for this ..It won help u..Jumbled sent n correct incorrect sent are a little confusing..it depends on ur grammer n English language skills.  do the comprehension last(it is a very big passage..i didn’t even read  it ,jus ticked..no time)
3.Attention Details (20 Q, 20 Min)
Find the odd man out
Analogy of figures (Simple)
syllogism
Puzzle
Very easy compared to other sections..any one can crack it with out any preparation..If u think to prepare jus go through puzzle test n syllogism from R.S.Agarwal Verbal reasoning
Analogy of figures –Non verbal Reasoning

TCS HR/TECHNICAL ROUND questions

TCS HR/TECHNICAL ROUND 2012/2013

Hello Folks
His post will discuss the details of the technical/HR (2nd) round for the TCS placement process. I have
included mine and some of my friends experiences. Basically there are 2 rounds for TCS. Once you clear
the aptitude(In my college 127 out of 232 cleared aptitude) you have to attend a pure HR , HR/Tech or a
pure Tech interview round. Yes it might sound odd but there are 3 types of panels(HR , HR/Tech or a
pure Tech) and depending on which one you go to the type of questions asked vary. The following are
the type of questions asked in each panel, I have tried my best to get all possible questions asked to the
127 that attended.
Each interview lasted approximately 10-15 minutes no more.There will be three interviewer, 2 will ask
you questions while the third interviewer listens and takes notes. And yes make sure you can answer
questions asked from your resume they do read it unlike most companies. You will be given a print out
of your camous commune application form.
Pure HR Panel:
Easy to clear for the most part, IT IS REALLY CRUCIAL THAT YOU SPEAK GOOD ENGLISH OR ATLEAST TRY
". As far as i have seen most people with good English speaking skills were selected
Asked to give a self introduction about themselves(refer to the post which i made,should give a good
idea)
"Are you ready to go anyway we send you are is there a particular place you like most?"
"Do you have a Girl Friend how long have you been together?"(for boys ofc)
They will ask you about your hobbies, if you say painting for example they will ask what you have
done to improve your skills in it.
"What is your fathers job?" or "How many brothers and sisters do you have?". For most of the HR
interviews there was always a family type question, shouldn't be a problem.
The biggest challenge you have faced so far in college
Why you choose your department and your favorite subjects (basically questions related to why you
choose the department and your interests).
THEN THE STRESS TEST: expect questions like "you have a low score in your aptitude why?", "your
marks are consistently low why ?", "You don't sound confident is that why you are speaking so softly ",
"you are an emotional person is it not , you look very tense".Remember these statements may or may
not be true about you try reply with a smile and positive comment like "I will try hard next time " or "I
will do correct these mistakes" etc. Just don't burst into tears like some of the girls in my college did
NOT GOOD!!!
"How badly do you want this job?"
And of course the most common questions "what did you eat in the morning? ",maybe a slight
variation like "you look tired have you had your lunch".
Then there was some questions on details about the company like "who is the CEO", "What do you
know about TCS", "Do you know what sector in IT TCS working". For these make sure you visit the
campus commune website and read all the details.
"What are you expecting from TCS?". For this just prepare a well rehearsed answer like "To improve
my skill and abilities in such a way that it is mutually beneficial to company and me"(What 2 of my
friends said , both selected of course)
Some questions from the resume, your co-curricular achievements , extra-curricular achievements. In
some cases the programming languages you know about.
Then some of the HR's asked questions logical questions like "Two people start from Delhi and Pune
one traveling at 20km/hr and the other 160km/hr in opposite directions both meet at a point who is
closer to Pune?" The answer is easy both as same distance since it is mentioned that they meet, THE KEY
HERE IS TO LISTEN CAREFULLY TO WHAT THEY ARE SAYING, some of my friends from other colleges did
not answer and thought the one going at 160km/hr was closer.Be prepared for questions of this type
testing your concentration.
"Are you going to do higher studies some time?"
"what is the hardest data structure for you "My friend said Trees, the HR are was like "Trees really
what about graphs, the LOLed real loud"
"about the various certification programs you have completed and why you took them"
Tech Panel:
To be honest this isn't hard really, all questions are simple nothing deep and tuff. Some of the
Interviewers did not even look at the code my friends wrote they just took the paper and used it as
paper fans :),
Programming, Data Structures and project related
"Write a java code using try catch statements"
"Explain about your project, implementations, front-end, back-end, technical details etc" BE extra
through about the details of all your projects
"code to implement a link list in C". "write it using pointers"
Some will ask you to write code from your projects(For some mechanical students theory behind
functionality of the project)
swap function without using temp variable
Explain linked list concept /stack/queue/trees
Explain different types of sorting
What is a null pointer, void point and a wild pointer
Explain the object oriented concepts in java(polymorphism,inheritance,encapsulation )
Then the sizes for various data types in C and Java
Program using thread/overriding/overloading in java.
Infix/postfix/prefix convertions
Java database connectivity.
what is a constructor?
other programs like prime numbers, odd/even easy stuff basic programming
Networks and OS
OSI layers in network model and functions of each layer
difference between TCP and UDP
"there are 2 systems in 2 different networks will you use a switch or a router to connect them"
What is the difference between switch, router , bridge
In OS questions related to the fork() command
Scheduling algorithms in OS
What is a semaphore
How many bits in an IP address
Draw a rough sketch of an IP packet
Layers of TCP/IP
A few questions related to the linux file system
Questions related to network address and host address
How is windows 7 different from XP
what is paging and questions related to that.
process life cycle
What is the ping command used for?
Database and Testing
This was all really easy MySQL queries which included select statements using where condition etc,
very easy queries.
Also some questions about normal forms, 1NF ,2NF, CNF.
Black box and white Box testing differences
Types of testing?
What is a test case?
Software life cycle models(waterfall models etc)
what is meta data?
Why is testing important?
This section had the most easiest of all questions, just study all the basics.
Other Department Students Tech Panel
Yes there is programming but it is not that deep here are a few samples
"explain about your project "(most frequent question asked to 78.9% students i got this information
from)
Then the interviewer asks what programming languages you know (most replied C), then he asks you
to write a simple programming like prime numbers ,swap without temp etc. In some cases write any C
program
To some EEE students the interviewer has ask how the ceiling fan/generator etc works
4 Mech students and 1 ECE student told me that the HR asked them their favorite subject and asked
him to explain about it
"what is CAD(he had CAD in his resume)"
Some questions related to data structures basics "what is stack"
Overall Pragramming and OS concepts are not going to be asked much unless you say you know
them.For example if you say you know java obviously he is going to ask a lot from it. Mostly others
departments had HR questions only or HR/tech.Everyone i asked said it was nothing tuff.Make sure you
know C programming , at least the basics.
Tech/HR panel
This is a mix and smash of both types of questions . Basically one HR will ask a tech questions and the
second HR will ask a HR questions. My friends kept on talking for all the HR questions he says it help
reduced the number of tech questions asked to him (I do not know the degree of effectiveness of this
idea :) ). By far these type of panels are easy to clear too.
After a few interviews it should be clear which panel is of which type. In my college the placement
representatives were responsible of putting you in a panel, just talk to them depending on which panel
you feel comfortable with.
Some important things
Speak clearly, most of the students who were selected could speak good English
Try not to sweat a lot, lots of interviewers ask they questions
Keep a separate copy of your resume in a stick file.
They was a incident in our college relating to under-performance. Basically some of the students who
were already placed went in and said they were placed in such and such company and they don't want
to come to TCS etc or that they don't like going for a job and want to do higher studies. DO NOT DO THIS
IT PISSED OFF THE INTERVIEWERS AND RESULTED IN LESS PLACEMENT COUNT AND IS REALLY RUDE. The
head of HR mentioned it during the closing ceremony. IF you want to under perform then do it without
it being too obvious. This incident happened in 3 colleges so far as I know, remember do not let your
actions effect other :) .(tell your friends who are planning on under performing this)
try wear a tie for boys and girls no high heels(one of the girls in my college tripped and fell in those ).
I do not know the degree of truth in this but most of my friends were saying that the female
interviewers were hot but deadly, since they asked the most questions and their interviews lasted the
longest
One more thing in my college students with cgpa over 7.5 had direct interview and those with < 7.5 had
to write aptitude which was tuff. Overall the hr/tech round is not that difficult just be calm and you can
clear it easy. Those who were selected got the offer letter on the same day through campus commune.
Good luck and feel free to ask any questions
