CSC ROUND3: GD (JAM)

This is the main round of elimination. Don’t get afraid But be prepared.

A group of 10 members will be called and given a topic. On a random

order u’ll be called to speak individually for 2 mins. Don’t worry the

moderator wont even look at u. he’ll keep listening to ur speech thru his

ears. They mainly expect how confident r u expressing from ur mind

without fear. So drive out fear completely. The other factors a

pronunciation n clarity (without stammering).

“Wat u speak doesn’t matter But How u speak Matters a lot in GD/JAM”

Few Sample Topics:

o My worst vacation

o We all make mistakes

o The most unforgettable Dream

o External outfit

o What do I fear for?

o The first day of my college

o My seniors in college

CSC ROUND4: TECHNICAL HR

Be confident in this round. They mainly check how confident r u in

answering. If u get thru this u r almost selected.

Prepare to be ready to answer

• About ur project

• C & C++ (even they will ask u write programs)

• Any question from ur area of interest. (DBMS & DS have more

advantage than OS/Networks)

• Basics in all subjects

TEST-1

H.R-primary key n foreign key multithreading and multiprograming

me-told

After that she had given me some puzzel.

there are 3 boxes in 1st contain red ball,in 2nd white,3rd mixture of white

n red in how many attempt u will find out which box have which color of

ball.

cut a cube in to 27 equal pieces and if all side of cube is painted then how

many piece of cube remain unpainted in 27 pieces of cube.

Then asked me about the Logic of Prime no,Bubble sorting,linked

list,merge sort etc.(Basics),One logic based on the odd no i don't

remember exactly.

TEST-2

NETWORKS

1) whn u open web browser, thn wht will happen wht do u do first thing?

2) wht u write first thing, i said DNS or webaddress concept thtn he asked

complete web adress like i told

http//:www.orkut.com

thn he asked meaning of each word-http,www,com etc

3) wht is URL

4) tel complete procedure how a site open after opening explorer

5) other layers understand DNS or not if not thn wht will happen (concept

of mapping to ip adress comes here) thy asked how mapping takes place

and at wich layer

6) dns procedure use wht tcp/ip or osi

7) how many layers in tcp/ip and wich layers are extra in osi model

8) tcp/ip conection oriented or conectionless

9) wht is DNs he was trying to ask in detail but as i havnot read so i said

tht

10) wht is arp

11) wht is rarp

12) wht is ATM(asynchronous mode transfer)

DBMS

1) wht is primary key

2) if ther is no primary key how will u uniquely identify each tuple (i said

composite key or super key)

3) diff between tuple and attribute

4) wht r anomalies explain each in detail (like insertion anomaly deletion

and modification anomaly)

5) wht is foreign key constraint

6) if i want to delete a tuple from a table having reference in so other

table thn wht will happen (concept of cascade comes else error)

7) wht r triggers explain

8) if i want to hav som tuples havind null value wht to do (outer join)

9) wht if i join two tables and no primary key (spurious tuples generate

redundant data)

10) he asked me wht will u do if need to retrieve this so basically query

and select first four tuples

select *

from employee

where salary

thn apply rownum<=4 to select first four tuples

11) diff betweenoracle 9i and oracle 8

12) diff between dbms, rdbms, ordbms

OS

1) wht is os

2) wht is a process

3) diff between process and thread

4) if threads share data section wht will happen

(concept of semaphore and crtitcal section comes so )

5) wht is semaphore

6) wht other thing semaphore do except synchronisation

7) wht else happen in threads and process so deadlock concept comes

8) deadlocks, and i told abt 4 conditons of deadlocks also

9) in os wher do u use stacks and queues

(like stacks for saving process satate , on system call context switch etc

and queue in scheduling so he asked do we hav only fifo scheduling)

10) so types of scheduling

Data Structure

1) u hav fifteen boxes in kitchen and ur mom asked u to make foos for 1

month, wht will u do to make food fast (thn concept of sorting came)

i said i will put name tag on boxes and thn sort thm in ascending order or i

can put thm in order of color shade firstly lightest and thn little darker and

soon but tht can create confusion so first is better way

2)u hav 1000 names in unorder manner and i asked u to pick any name of

my choice randomly and thn giv me complete info of tht person so wht ds

will u use

i said firstly i will sort thm thn i will use hashing/btrees as thy r faster in

decreasing search domain,

thy asked wich sort will u use

i said radix as good for strings , he asked if one more name increase or

decrease i said radix sort take linear time so doesnot affect much on time

he said if names r vary in length like one is venkateshraman other is raj i

said sort from 3rd last letter or use padding.

3) wht is heapsort, concept . wher u can apply it

4) wht all ds u know

i said heaps binomial fiboncaai, liked list stacks queues trees arrays etc

5) advantage and disadvantage of linked list and array over each other in

temrs of memory allocation

6) insert and delete a node in a linked list write a code(not from me)

basically thy asked asll application based question on data structure

java/c/c++

1) write a java code of swapping to name via calling object as parameter

and asked whther result will reflect in main or not

(as object passed as a reference so reuslt will be reflected)

2) in java we use call by reference or call by value

paper.plss read the qstns and answers which i give and all are right

answers...prepare previous papers ,its enough..and aptitude paper

consists of 40 questions in 40 mins.tech paper is very easy....but aptitude

is tuff......prepare aptitude......... the tech paper is asa follows

1.WSDL is associated with webservices.

2.BLOB is any large single block of data stored in a database, such as a

picture or sound file, which does not include record fields, and cannot be

directly searched by the database’s search engine.

3. cache memory is a reserved area of the immediate access memeory

used to increase the running speed of the computer program.

4. DMZ is a small subnet that sit between atrusted internal network and

an untruster external network, such as the public internet.

5.RFID technologies that use radio waves to automatically identify people

or objects,which is very similar to the barcode identification systems,seen

in retail stores everyday.

. APTITUDE TEST:

This paper consists of 40 qstns to be solved in 40 minutes.This section

was moderate(not so difficult).

-->One qstsn was on propabiltity like there are 3 piles of books.Each

containing 6,5,4 books.What is the propability that first book will be

arranged and so on.. ans: 12!

--->One qstn on profit and loss..

--->one qstns on speed and distance.

--->there were 3 fill ups with suitable words. (easy)

--->there were 5-6 passages (all easy)

--->there were 3-4 analogies.

--->one qstns on permutation.

--->one qstn was on ages..

---->two qstns were from ratios.

---->Then one one problem from geometry containing 3 sub-qstns.(See

BARRONS GRE.it would be helpful)

---->One function like f(0,x)=x+1

f(0,y)=y

f(0,0)=1

f(x,y)=f(x+2,f(y-1))(not the exact qstns but similar like that) then find

f(1,1),f(3,0).f(1,2),then derive f(3,0) in terms of f(0.0),f(1,0),f(1,2).Totally 5

sub qstns ..all were easy..

---->One Sudoku problem..A 3*3 block in which only 2 blocks were

filled.The remaining bloxks had to be filled such that diagonally,vertically,

horizontally it should sum up to 15..based on this 5 easy qstns were

given..

The results were out.total 951 students attented the test in that 370

selected for next round. I was shortlistd for the second round (JAM)..

3. JAM (COMMUNICATION TEST)

Here ,we were given a topic and to speak on that for about a minute. My

batch had "TECHNOLOGY vs AGRICULTURE". Other batches had "ROLE

MODEL", "WOMEN IN SOCIETY","3 IMPORTANT PROBLEMS OF INDIA",

"TELL ME ABOUT UR SELF". my batch consists of 20 members.3 cleared

the JAM round..luckly i am one among them.......MAXIMUM elimination is

here......bcarefull guys.................


Be confident with ur basic skills (C,C++).If you are of ECE be confident

with your core knowledge.It helps you a lot.Be cool as much as you can.i

am from CSE...the questions asked is

1. tell me ur project?

2.primary key?

3.normailsation?

4.double linked list?

5.IP adress?

6.diff between TCP and UDP?

7.bubble sort?

8.different types of databases?

9.basics on .net(i used .net technology in my project)

10.unix?

5. HR INTERVIEW

It is a normal round checking your communication skills and your personal

skills.Be bold and confident.You would definitely go through this round. no

questions for me in this round..........because of my percentage and tech

round score....directly HR said that "U R SELECTED FOR

Along with this paper you would be given 4 topics(ESSAY WRITING).Here

we have to chose one topic and write an essay.i wrote on "PARENTS ARE

THE BEST TEACHERS"

The results were announced in half an hour..I was shortlistd for the secod

round.The next round was Aptitude Test.

2. APTITUDE TEST:

This paper consists of 40 qstns to be solved in 40 minutes.This section

was moderate(not so difficult).

-->One qstsn was on propabiltity like there are 3 piles of books.Each

containing 6,5,4 books.What is the propability that first book will be

arranged and so on.. ans: 12!

--->One qstn on profit and loss..

--->one qstns on speed and distance.

--->there were 3 fill ups with suitable words. (easy)

--->there were 5-6 passages (all easy)

--->there were 3-4 analogies.

--->one qstns on permutation.

--->one qstn was on ages..

---->two qstns were from ratios.

---->Then one one problem from geometry containing 3 sub-qstns.(See

BARRONS GRE.it would be helpful)

---->One function like f(0,x)=x+1

f(0,y)=y

f(0,0)=1

f(x,y)=f(x+2,f(y-1))(not the exact qstns but similar like that) then find

f(1,1),f(3,0).f(1,2),then derive f(3,0) in terms of f(0.0),f(1,0),f(1,2).Totally 5

sub qstns ..all were easy..

---->One Sudoku problem..A 3*3 block in which only 2 blocks were

filled.The remaining bloxks had to be filled such that diagonally,vertically,

horizontally it should sum up to 15..based on this 5 easy qstns were

given..

The results were out. I was shortlistd for the third round (JAM)..

3. JAM (COMMUNICATION TEST)

Here ,we were given a topic and to speak on that for about a minute. My

batch had "SOCIAL RESPONSIBILITY". Other batches had "ROLE MODEL",

"3 IMPORTANT PROBLEMS OF INDIA". Unfortunately, HR was unimpressed

with my speech. But,frnds talk loudly,with confidence.Express your ideas

with a clarity in your ideas.Dont take lite,as this your chance to show who

you are.So,try to give your best shot.. Dont pause.Keep a smile on your

face.Around 22 were shortlistd for the TECHNICAL INTERVIEW round.


Be confident with ur basic skills (C,C++).If you are of ECE be confident

with your core knowledge.It helps you a lot.Be cool as much as you can.

5. HR INTERVIEW

It is a normal round checking your communication skills and your personal

skills.Be bold and confident.You would definitely go through this round.

May GOD bless you..

Friends for technical test these questions are enough, but aptitude test

some what tough, for this u must go through RS AGRWAL , this is enough

to qualify these 2 tests

ROUND III. Communication Round:(Maximun elimination)

It was a one to one interaction with the panel where they check ur

fluency, and grammar n pronunciation. Be very sure that u don’t stop

while speaking. Just keep on speaking without stammering until the panel

personnel asks u to stop The communication round mainly includes

introduce yourself and some question that he may ask of his choice.

ROUND IV. (Technical Interview)

Question from each and every technical aspects will be asked like

Questions on Pointers, OOPS concepts, Deff b/w DBMS and RDBMS,

Projects you have done (UG&PG), OS (UNIX,WIN), etc..sql,java,data

structure even question from the techincal written round will be asked 2

explain so dont just remember the answer of written round try to

understand the reason of answer.

But something new happened at my stage. When my name came up I got

in and asked for permission.then he offered me a seat.and asked to tell

something abt myself.then he asked

1.how do u rate urself in c & c++. I said in c its 7 and in c++ its 8.

2.why there is a difference?i replied that though I know all concepts of c,

but rightnow I have not much idea abt linked list,stack,tree.

3.well if I will say u to implement linked list using c++,can u do it? I

replied yes sir.this is possible.but as I said I am unable to do it right now.

4.what is early binding & late binding? I explained with examples.

5.what is virtual?explain with example?I explained .

6.can u define a class in real life? I explained with 3 examples.

7.wap to insert & retrieve data into a 3d matrix?i did.

8.He said well u r good .ok foget abt this technical aspect.Can I ask u qts

from any other aspects.i said sure sir.it will b my pleasure.

9.then he asked.There r 9 balls having equal volume,equal color.But one

of them is slightly heavier than the rest.now u tell me the shortest way to

find out the heavier one?..I replied there r 5 ways.He behaved like

surprised n said I asked the same qt to some people and got answers in 2

ways.Ok u name the five ways.i did based on Archmedis principle,law of

physics .but he was not satisfied and asked me what is the shortest way.I

replied sir I need time to answer.He said ok. Then he kept on asking qts n

I was answering.During my leave, He asked what is d shortest way.I said I

wll definitely t ell u sir wheather I will b selected or not.

10.well saroj it was a nice conversation with u.good luck.i said thank u sir.

ROUND V (HR Interview)

Hr is just a formailty if ur technical round has gone very well.

1. Tell me about yourself in brief???

2. What r ur hobbies/?i answered body building.then he asked abt the gym

n exercise

3.have u heard abt CSC before??

4.R u ready to work anywhere inside/outside india?? i gave a big "Yes sir"
