Technical Round

Q1. Introduce yourself.

The first question in most of the interviews is usually to introduce yourself.Prepare a crisp answer about the things you have done,technologies you work on,internships and projects you have done.talk about anything you are confident about.this answer will decide the further questions of the interviewer and will give a direction to your interview.so,don't forget to mention about your most confident skills and anything you want to discuss and talk about.

Sample Answer:

hello , My name is XYZ from ABC college IT branch.In my 4 years at college I have worked to explore both technical and non technical part in me.I have worked with PQR firm where i have worked on android development. My major work was to work on the UI part of the application. Along with that I have participated in various hackathons and coding challenges. I have worked on few personal projects in my college like...(mention 1-2 in short).

Tips: talk about your confident part in a very humble way.Introduction part can take up  around 2-3 mins. 

Q2.Which programming languages are you proficient in?

As an engineering student, it is likely that you have worked on many programming languages, Please refer about the language you have worked on the most and you are confident in both coding as well as theoretical concepts about that language.

Sample Answer:

I have worked on languages such as Java,C++ and JavaScript. Out of these I am most confident about Java. I have worked on my major projects in Java.

Q3. What are the differences between for loop and foreach loop.

FOR LOOP	FOREACH LOOP
It runs until the given condition becomes false	It runs until last element in the array
It is flexible to iterate in both ascending and descending order.	t runs from starting to end of array. It is read only loop.No manipulation on data can be done.

Tips: Mention at least 2 points that clearly specify the difference between the things.

Q4.Name all the sorting techniques and their worst time complexities.

SORTING ALGORITHMS	WORST CASE TIME COMPLEXITY
Bubble sort	O(N^2)
Selection Sort	O(N^2)
Insertion Sort	O(N^2)
Quick Sort	O(N^2)
Merge Sort	O(NlogN)
Heap Sort	O(NlogN)

Q5. Write the pseudo code for bubble sort.

for(int i=0;i<n-1;i++){
            for(int j=0;j<n-1;j++){
                if(arr[j] < arr[j+1]){
                    swap(arr[j],arr[j+1])
                }
            }
}

Q6. Write the pseudo code to check whether a number is prime or not

 int flag=1;
        for(int i=2;i<sqrt(n);i++){
            if(n%i==0){
                flag=0;
                break;
            }
}

Q7. Define different OOPS Concepts.

Inheritance - When one object acquires all the properties and behaviors of a parent object, it is known as inheritance. It provides code reusability. It is used to achieve runtime polymorphism.

Encapsulation - Binding (or wrapping) code and data together into a single unit are known as encapsulation. For example, a capsule, it is wrapped with different medicines.

Polymorphism - If one task is performed in different ways, it is known as polymorphism. For example: to convince the customer differently, to draw something, for example, shape, triangle, rectangle, etc.

Abstraction - Hiding internal details and showing functionality is known as abstraction. For example phone call, we don't know the internal processing.

Q8.  What is operator overloading in C++?

C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading.
For example, we can overload an operator ‘+’ in a class like String so that we can concatenate two strings by just using +.

Q9. What are different types of inheritance in C++?

Single inheritance is defined as the inheritance in which a derived class is inherited from the only one base class.
Multiple inheritance is the process of deriving a new class that inherits the attributes from two or more classes.
Hierarchical inheritance is defined as the process of deriving more than one class from a base class.
Multilevel inheritance is a process of deriving a class from another derived class.
Hybrid inheritance is a combination of more than one type of inheritance.
