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:

• My worst vacation
• We all make mistakes
• The most unforgettable Dream
• External outfit
• What do I fear for?
• The first day of my college
• 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.

• 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
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
3) wht r interfaces
4) diff between interfaces and abstraction

question from the techincal written round

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

4.what is early binding & late binding?
5.what is virtual?explain with example?
6.can u define a class in real life?
