Why should I hire you?
This is an important Question for Every Campus interview - Practice a good Answer Here!
By now you can see how critical it is to apply the overall strategy of uncovering the employer’s
needs before you answer questions. If you know the employer’s greatest needs and desires, this
question will give you a big leg up over other candidates because you will give him better reasons
for hiring you than anyone else is likely to…reasons tied directly to his needs.
Whether your interviewer asks you this question explicitly or not, this is the most important question
of your interview because he must answer this question favorably in is own mind before you will be
hired. So help him out! Walk through each of the position’s requirements as you understand them,
and follow each with a reason why you meet that requirement so well.
Example: “As I understand your needs, you are first and foremost looking for someone who can
manage the sales and marketing of your book publishing division. As you’ve said you need
someone with a strong background in trade book sales. This is where I’ve spent almost all of my
career, so I’ve chalked up 18 years of experience exactly in this area. I believe that I know the
right contacts, methods, principles, and successful management techniques as well as any person
can in our industry.”
“You also need someone who can expand your book distribution channels. In my prior post, my
innovative promotional ideas doubled, then tripled, the number of outlets selling our books. I’m
confident I can do the same for you.”
“You need someone to give a new shot in the arm to your mail order sales, someone who knows
how to sell in space and direct mail media. Here, too, I believe I have exactly the experience you
need. In the last five years, I’ve increased our mail order book sales from $600,000 to $2,800,000,
and now we’re the country’s second leading marketer of scientific and medical
books by mail.” Etc., etc., etc.,
Every one of these selling “couplets” (his need matched by your qualifications) is a touchdown that
runs up your score. IT is your best opportunity to outsell your competition.
What the interviewers Look for in an Interviewee
The interview panel members assess the candidate by asking him/her a variety of questions and
looking at the candidate's responses for these questions . Whatever be the questions asked, they
look for certain qualities and attributes in the candidate. Whenever the interviewers ask you a
question, they will have an objective in mind . Before you response to the question, you should be
aware as to what the question is basically about and what facet of your personality is being tested
through that question. If you have that understanding, you will be able to respond to the question in
a suitable and object-oriented manner.
The main qualities that the interviewers look for in the candidates are:
Level of knowledge the candidates possesses
conceptual understanding of issues
clarity of thoughts
communication skill
Planning of career
Basic personality
Reacting to a situation
Top interview Questions:
Tell me about yourself?
Bad answer:
“I graduated four years ago from the University of ICFAI, with a Bachelor’s in Biology – but I
decided that wasn’t the right path for me. So I switched gears and got my first job, working in sales
for a startup. Then I went on to work in marketing for a law firm. After that, I took a few months off
to travel. Finally, I came back and worked in marketing again. And now, here I am, looking for a
more challenging marketing role.”

What 1.What is the difference between C and Java?
1.JAVA is Object-Oriented while C is procedural.
2.Java is an Interpreted language while C is a compiled language.
3.C is a low-level language while JAVA is a high-level language.
4.C uses the top-down approach while JAVA uses the bottom-up approach.
5.Pointer go backstage in JAVA while C requires explicit handling of pointers.

2.What is the difference between array and pointer?
Pointer is a variable in a program is something with a name, the value of which can vary. The way
the compiler and linker handles this is that it assigns
a specific block of memory within the computer to hold the value of that variable.
An array is a conceptual data representation consisting of a list of more than one item of a
particular scalar type (int, float, char, structure, etc.) where each element is accessed by its
index.3.What is the difference between Strings and Arrays?
- String can hold only char data. Where as an array can hold any data type.
- An array size can not be changed. Where as a string size can be changed if it is a char pointer
- The last element of an array is an element of the specific type. The last character of a string is a
null – ‘\0’ character.
- The length of an array is to specified in [] at the time of declaration (except char[]). The length of
the string is the number of characters + one (null character).
3.What is Recursion Function?
a) A recursive function is a function which calls itself.
b) The speed of a recursive program is slower because of stack overheads. (This attribute is
evident if you run above C program.)
c) A recursive function must have recursive conditions, terminating conditions, and recursive
expressions.
5.Diffrence between default and copy constructor?
4.What are abstract class?
An abstract class is a class which does not fully represent an object. Instead, it represents a broad
range of different classes of objects. However, this representation extends only to the features that
those classes of objects have in common. Thus, an abstract class provides only a partial
description of its objects
5.Define Deadlock?
In an operating system, a deadlock is a situation which occurs when a process enters a waiting
state because a resource requested by it is being held by another waiting process, which in turn is
waiting for another resource. If a process is unable to change its state indefinitely because the
resources requested by it are being used by other waiting process, then the system is said to be in
a deadlock.
6.What is linked list?
Linked list is one of the fundamental data structures, and can be used to implement other data
structures. In a linked list there are different numbers of nodes. Each node is consists of two fields.
The first field holds the value or data and the second field holds the reference to the next node or
null if the linked list is empty.
7.What is the difference bet do loop & do while loop?
The difference between a "do ...while" loop and a "while {} " loop is that the while loop tests its
condition before execution of the contents of the loop begins; the "do" loop tests its condition after
it's been executed at least once. As noted above, if the test condition is false as the while loop is
entered the block of code is never executed. Since the condition is tested at the bottom of a do
loop, its block of code is always executed at least once.10.What is polymorphism & inheritance
property?
Polymorphism is the ability to use an operator or function in different ways. Polymorphism gives
different meanings or functions to the operators or functions. Poly, referring to many, signifies the
many uses of these operators and functions. A single function usage or an operator functioning in
many ways can be called polymorphism. Polymorphism refers to codes, operations or objects that
behave differently in different contexts.
8.What is OOPS concept?
Object-oriented programming (OOP) is a programming paradigm using "objects" – data structures
consisting of data fields and methods together with their interactions – to design applications and
computer programs. Programming techniques may include features such as data abstraction,
encapsulation, messaging, modularity, polymorphism, and inheritance. Many modern programming
languages now support OOP, at least as an option.
9.What are dynamic and static memory location?
The allocation of memory for the specific fixed purposes of a program in a predetermined fashion
controlled by the compiler is said to be static memory allocation.
The allocation of memory (and possibly its later deallocation) during the running of a program and
under the control of the program is said to be dynamic memory allocation.
10.Write a program in C to sort a list of numbers in ascending order?
11.Write a program in java to print the odd no. between 1 to 100?
12.What is the differentiate b/w analog and digital communication?
13.What is the difference between Truncate and Delete?
14. What is the difference between DBMS and RDBMS?
15.What are the advantages of SQL?
These are the advantages of PL/SQL.
Block Structures: PL SQL consists of blocks of code, which can be nested within each other. Each
block forms a unit of a task or a logical module. PL/SQL Blocks can be stored in the database and
reused.
Procedural Language Capability: PL SQL consists of procedural language constructs such as
conditional statements (if else statements) and loops like (FOR loops).
Better Performance: PL SQL engine processes multiple SQL statements simultaneously as a
single block, thereby reducing network traffic.
Error Handling: PL/SQL handles errors or exceptions effectively during the execution of a PL/SQL
program. Once an exception is caught, specific actions can be taken depending upon the type of
the exception or it can be displayed to the user with a message.

19.What is the basic difference between a Join and a Union?
Union:
It combines the results of two or more queries into a single result set consisting of all the rows
belonging to all queries in the union.
Basic Rules:
The number and the order of the columns must be the same in all queries.
The data types must be compatible.
Join:
To retrieve data from two tables or more than two tables then use joins.
Types: Inner Join, Outer Join(Right outer join, left outer join), cross join, Equi join, Self join.
The number and the order of the columns need not be the same in all queries.
20.what is a root?
"root" refers to the top-level directory of a file system. The word is derived from a tree root, since
it represents the starting point of a hierarchical tree structure. The folders within the tree represent
the branches, while the actual files are considered the leaves. However, unlike a real life tree, a
data tree can be visualized upside down, with the root at the top and directories and subdirectories
spanning downward.
The root node of a file system is also called the root directory. On a Windows-based PC, "C:\"
represents the root directory of the C drive.
If you ever use a terminal program to view files and folders on a computer, you can use the
command "cd /" (change directory to root) to navigate to the root directory.
"Root" is also the name of the user who has administrative privleges on a Unix or Linux server.
