Hi Chetanaites

I am Suraj Manekar. Persistant Came To Our Campus on 4th of April. They Have Two Test - One On General and second on Programming. They Have Changed Their Paper Pattern. Now There Was 15 Qt Questions On Quanti with analytical, 10 on C, 10 on DSA and No DBMS No Toc, And Only 5 OS Question

FIRST SECTION

a) Quati Section   15 marks
i) analytical
ii) quanti

b) C Section       10 marks
c) DSA section     10 marks
d) OS section      5 marks

C section:
1 main()
{
printf("persistent");
main();
}
ans:print the persistent till the stack overflow occur

2) f(0)=0;   
f(16)=?
int f(int n)
{
if(n>100)
n=n-10;
else
something
}
ans 91;

3) question on seek() i.e. moving file pointer pointer has to point just before the last character of the file os) what is thrashing?

DSA
1) find number of nodes in complete binary tree of level 5
 ans:-63

SECOND SECTION
There were two programs on C
1) create doubly linked list
2)second question was on graph there is one undirectional connected graph and we have to find connected edges in a graph user input the adjacency list /matrix http://www.ChetanaS.org
Hint: first find out the path matrix by warshals algorithm then from this matrix u will get which are the connected nodes which not in matrix 0 means unconnected 1 for connected

FIRST TECHNICAL INTERVIEW
The most important round in which u ask to write a program
1)i ahve asked to write a program on finding a position of number in fabonaci series.
2)finding a liked list whether it is looping linked list or general linked list
3)to write a program to create linked list.
4)virtual function of C++.
5)calloc and malloc
6)operator overloding
7)static variable
8)how to allocatte dynamic memory.
9)what is big o nation
10) all sorting alogorithm and their complexity

SECOND TECHNICAL INTERVIEW
They can ask u tell the differenrt technical area of interst than C, C++, DSA. if u have so.
1) Puzzle on cutting cake in 8 same parts using only three cuts.
2) multithreding, multitasking, multiprocessor system
3) wrte a program reverse the integer no.
4) write a program to draw square without using  recatangle function in C++.
5) FAT, NTFS, windows NT, WINDOWS XP.
6)warshalls alogorithm, dijkstra algoriyhm
7)query on sql to find the names of the person who is having same name.
8)linux give the command which tells the process status
9)softare engg.
10) software development life cycle.
 
THIRD ROUND HR
