Campus Written Test conducted in 3 at Bangalore
The test comprises of 2
sections:
1. Technical ( C ) & Technical Subject- 60 mins, 60
questions
2. Logical Reasoning.. - 30 mins,17
questions....
==>
Questions in C were mostly from "pointers in c" and "test ur C
skills" by Yeshwant Kanetkar... C questions based on command line
arguments, data structure ( BST, tree traversals). All the questions
were like " what is the output of the following program segment" and
in many questions 3rd and 4th choices were (c) compilation error and
(d) compilation, warning, runtime error.... Heard they are
asking abt- ptr, string, arr, preprocessor, data structures
etc.. C test was pretty ok pass by value, pass by
reference etc. questions were asked The general test was pretty
tough, they ask u fourier transforms,harmonics,Barkhuasen
criterion,virtual memory,Whether FIFO is better than LRU etc. 4
questions were from fourier transforms the duration was 60 mins and
no negative marking
C basics 10
questions ,very easy.Given a program and asked the output-type
questons.from pointers 3-4 questions are there. 2)reg subject:very
very easy:some from digital(on nand gates. Jk flip flop),from
Information theory and coding,some from Micro processors.
In Logical
Reasoning all the 17 questions were paragraphs (argument) of 5 to 6
sentences...five sentences (choices) will be given below and
questions were asked like " which of the five if true will weaken or
supports the argument above .." :- R. S. Agrawal LR is
sufficient

The questions were like
this.
------------------------------
The text consists of two
parts
1) C test
2) CSE01 Test
Duration:
1hr
---------------------------------------------------------------
1)
C test -10 questions- Some questions were as follows, remember
only a few.
a) What is the parameter passing mechanism to Macros
Called?
b) void func(int x,int
y)
{
x=3;
y=2;
}
Freshersworld.com![]()
main()
{
int
i;
func(i,i);
print(i);
}
If the output must be 2 what
is the parameter passing mechanism called?
c) which of the
following code will swap the two numbers? -3 choices was given
d)
which of the following is illegal for the
program?
main()
{
char const
*p='p';
}
Freshersworld.com
1)p++ 2) *p++ 3)(*p)++ 4) all
e) what is
the output of the following program
void print(int **
arr)
{
print("0 %f, 1 %f, 2 %f
",arr[0][0],arr[0][1],arr[0][2]);
}
main()
{
int a[][]={
{1,2,3},
{4,5,6}
}
Freshersworld.com
int **
arr=a;
print(arr);
arr++;
print(arr);
}
f) which of
the following code swaps the two numbers.
- 4 choices were
given
g) if the string " this is a " is present in the code of a
function such as 'void func(void)' where
will the variable
stored in the memory.
a) in the stack b) heap c) code or text
segment as per implementation d) created when func is called, stored
in function stack space and destroyed as it goes out .
2)
CSE01-15 questions
In this section there was question from
LD-gates, JK flip flop, sampling rate and few other
then there
was a few from OS - don't remember the questions.

INTERVIEW
In the interview, they asked about Stacks,
Queues, Linked lists, Binary Trees.
Few questions I remember are:
1) If u have a linked list library, how do u
design stack and queue using it; write pseudocode.
2) What are static variables and functions?
3) Write code in C to count the number of 1s in a
character (1byte).
4) What is pre-order, post-order, in-order; write
code to print post-order.
5) Can u construct a binary tree given its
inorder and postorder details. Is it neccessary or sufficient to
construct tree. Asked an example to do in both ways.
6) If recursion is not used to print post order,
what other data structure u use
(ans: Stack).
7)Can u use stack always in place of
recursion?
(ans: Yes)
8) What are meta characters?
9) Write a piece of code to insert a node in a
linked list.
10) About malloc.
11) About Operating System - Semaphores
12) About Computability (eg:- finding infinite
loop), Complexity of algorithms
13) What does compiler and assembler do?
They asked grep command in Linux. How do u search
'\n', using grep, in a file.
They may ask some other commands if u say u r
familiar and recently been using linux.
About Networks? OSI reference model.
what does transport layer do?
TCP belongs to which layer?
IP belongs to which layer?
Where is error correction done?
What is a connection oriented/ connection less
transmission?
What is meant by reliable transmission protocol?
why is it called so?
What is flow control and where it is done?
About ur project?
Asked me expalin about the project in brief.
If u don't know anything, say it sincerely. U
cannot bluff them. I too spoke to them sincerely.
They were cool. U need not get tensed. They won't
attack you. Just they want to know ur hold about the subject.
