7)y=MAX((3x+y),(11x-y))then what's the value of y???

8)some passages were there based on illegal drugs smuggling and based on this some questions.

9)Some Analogy Questions: some i do remeber like SYCOPHANTIC: FLATTER SILENT:QUIET others i dont remember.

10)Some questions based onif f(x,0)=x+1f(o,y)=yf(x,y)=f(f(x,0),f(2*x-1))

then find f(1,1),f(2,3),f(3,0) etc and some relations based on this very easy11)One question based on the average speed12)one question based on Sudoku type very easy,u can do it in one attempt

TEST-2

1. Sudoku. you need to fill-up the table using the hint(addition of row, column, diagonal =15) and availablecell values. its easy. if you figure it out, you can answer(very easy)five questions correctly.2.If y=MAX((3x+y),(11x-y)) then what's the value of y?3.1 Que. on book arrangement. if u find out the series you can ans five ques. correctly.4.2 Ques. on Probability, ages5. Ages6. Venn diagram --> Out of 100 students, 45 do not know typing, 60 know shorthand. 25 know both 6 do notknow anything then find out haw many know both?7. if f(y,0)=y+1, f(o,x)=x; f(y,x)=f(f(y,0),f(2*y-1)) then find f(1,1),f(2,3),f(3,0); 3 question based on this. Itsvery very simple...8. 1 Ques on Percentage : Price of a book increases 15% successively (2times) what is the new price of thebook more compared to that of the old price:a)32.25% b)23.34% c)36% d)39%9. 2 Questions based on Time and speed.10.

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 becalled to speak individually for 2 mins. Don’t worry the moderator wont even lookat u. he’ll keep listening to ur speech thru his ears. They mainly expect how confidentr u expressing from ur mind without fear. So drive out fear completely. The otherfactors 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 vacationo We all make mistakes

o The most unforgettable Dreamo External outfito What do I fear for?o The first day of my collegeo My seniors in college

CSC ROUND4: TECHNICAL HRBe confident in this round. They mainly check how confident r u in answering. If uget 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-1H.R-primary key n foreign key multithreading and multiprogramingme-toldAfter 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 howmany 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 ofcube remain unpainted in 27 pieces of cube.Then asked me about the Logic of Prime no,Bubble sorting,linked list,merge sortetc.(Basics),One logic based on the odd no i don't remember exactly.TEST-2

NETWORKS1) 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 webadress like i toldhttp//:www.orkut.comthn he asked meaning of each word-http,www,com etc3) wht is URL4) 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 toip adress comes here) thy asked how mapping takes place and at wich layer6) dns procedure use wht tcp/ip or osi7) how many layers in tcp/ip and wich layers are extra in osi model8) tcp/ip conection oriented or conectionless9) wht is DNs he was trying to ask in detail but as i havnot read so i said tht10) wht is arp11) wht is rarp12) wht is ATM(asynchronous mode transfer)DBMS1) wht is primary key2) if ther is no primary key how will u uniquely identify each tuple (i said composite keyor super key)3) diff between tuple and attribute4) wht r anomalies explain each in detail (like insertion anomaly deletion andmodification anomaly)5) wht is foreign key constraint6) if i want to delete a tuple from a table having reference in so other table thn wht willhappen (concept of cascade comes else error)7) wht r triggers explain8) 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 queryand select first four tuplesselect *from employeewhere salarythn apply rownum<=4 to select first four tuples11) diff betweenoracle 9i and oracle 812) diff between dbms, rdbms, ordbmsOS1) wht is os2) wht is a process3) diff between process and thread4) if threads share data section wht will happen(concept of semaphore and crtitcal section comes so )5) wht is semaphore6) wht other thing semaphore do except synchronisation7) wht else happen in threads and process so deadlock concept comes8) deadlocks, and i told abt 4 conditons of deadlocks also9) in os wher do u use stacks and queues

(like stacks for saving process satate , on system call context switch etc and queue inscheduling so he asked do we hav only fifo scheduling)10) so types of schedulingData Structure1) u hav fifteen boxes in kitchen and ur mom asked u to make foos for 1 month, wht will udo 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 inorder of color shade firstly lightest and thn little darker and soon but tht can createconfusion so first is better way2)u hav 1000 names in unorder manner and i asked u to pick any name of my choicerandomly and thn giv me complete info of tht person so wht ds will u usei said firstly i will sort thm thn i will use hashing/btrees as thy r faster in decreasingsearch domain,thy asked wich sort will u usei said radix as good for strings , he asked if one more name increase or decrease i saidradix sort take linear time so doesnot affect much on timehe said if names r vary in length like one is venkateshraman other is raj i said sort from3rd last letter or use padding.3) wht is heapsort, concept . wher u can apply it4) wht all ds u knowi said heaps binomial fiboncaai, liked list stacks queues trees arrays etc5) advantage and disadvantage of linked list and array over each other in temrs ofmemory allocation6) insert and delete a node in a linked list write a code(not from me)basically thy asked asll application based question on data structurejava/c/c++1) write a java code of swapping to name via calling object as parameter and askedwhther 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 value3) wht r interfaces4) diff between interfaces and abstractionTEST-3HR: tell me about ur selfHR: well...r u familiar with C...

HR: WAP to print a pattern * ** *** ****HR: what is ur area of interest...Hr: write a program to add a node to a link list?Hr: have done any project.....HR: what it LAN?HR: what is MAC?HR: what is Modem?TEST-4Questions onPointers,OOPS concepts,Deff b/w DBMS and RDBMS,Projects you have done (UG&PG),OS (UNIX,WIN), etc..sql,java,data structurequestion from the techincal written round1.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 ideaabt linked list,stack,tree.3.well if I will say u to implement linked list using c++,can u do it? I4.what is early binding & late binding?5.what is virtual?explain with example?6.can u define a class in real life?7.wap to insert & retrieve data into a 3d matrix?There r 9 balls having equal volume,equal color.But one of them is slightly heavier than the rest.now u tellme the shortest way to find out the heavier one?

CSC ROUND5: PERSONAL HRThis round is for formality. But do this well. Be ready to answer stress related queslike “Have u gone thru previous year papers in sites?” or “Why r ur marks inconsistent

from school to college?”HR Questions

o Tell me something about yourself??o How did u write your written test???o Family Back Ground?o What's your strengths and weakness?o What r ur hobbies?o Who keeps you motivating towards your goal?o Do you hv any other offers with you right now?o why didnt u go to previous companies??o Why CSC?o Have u heard abt CSC before??o Which Platform do u want to work on?o Which environment u would like to work?o Are you flexible about locations in India and outside India?o Do u know the bond and condition that if u leave the company b4 2 yr,u will hav to pay a sum

of 1 lakh?o Do u have any qts ?

All the best! Regards,KAARTHIK KUMAR.T
