Published: 11 November 2026 | Author: CCI Admin | Category: Career
Starting your career in the IT industry is an exciting journey. However, attending your first technical interview can be challenging, especially for freshers. Many companies evaluate candidates based on their programming knowledge, logical thinking, database concepts, and problem-solving skills.
In this blog, we will explore the Top 10 Technical Interview Questions for Freshers with Answers to help students prepare confidently for their first IT interview.
1. What is Programming?
Programming is the process of writing instructions that tell a computer how to perform specific tasks. These instructions are written using programming languages such as Python, Java, C, and C++.
Example:
print("Hello World")
Output:
Hello World
2. What is the Difference Between C and Python?
C and Python are popular programming languages used for developing software applications. However, they differ in syntax, execution, and applications.
| C Programming | Python |
|---|---|
| Procedural programming language | Multi-paradigm programming language |
| Uses more syntax | Simple and readable syntax |
| Commonly compiled | Commonly executed using an interpreter |
| Used in system programming | Used in AI, automation, and web development |
3. What is Object-Oriented Programming (OOP)?
Object-Oriented Programming is a programming approach based on classes and objects. It helps developers create reusable and organized applications.
The four main principles of OOP are:
- Encapsulation
- Inheritance
- Polymorphism
- Abstraction
Example in Python:
class Student:
def display(self):
print("Welcome Student")
s = Student()
s.display()
Output:
Welcome Student
4. What is a Database?
A database is an organized collection of information that can be stored, accessed, managed, and updated easily. Databases are widely used in websites, banking applications, educational institutions, and business software.
Examples of databases:
- MySQL
- Oracle
- PostgreSQL
- Microsoft SQL Server
5. What is SQL?
SQL stands for Structured Query Language. It is used to communicate with relational databases and perform operations such as inserting, retrieving, updating, and deleting records.
Example:
SELECT * FROM students;
This query retrieves all records from the students table.
6. What is the Difference Between HTML and CSS?
HTML and CSS are essential technologies used in website development.
| HTML | CSS |
|---|---|
| Defines webpage structure | Controls webpage design |
| Creates headings, paragraphs, and forms | Adds colors, fonts, and layouts |
| Markup language | Style sheet language |
7. What is a Function in Programming?
A function is a reusable block of code designed to perform a specific task. Functions help reduce code repetition and improve program organization.
Example in Python:
def add(a, b):
return a + b
print(add(10, 20))
Output:
30
8. What is the Difference Between Compiler and Interpreter?
A compiler translates source code into another form, commonly machine code or executable code, before program execution. An interpreter executes program instructions through an execution environment.
| Compiler | Interpreter |
|---|---|
| Translates code before execution | Executes code through an interpreter environment |
| Commonly used with C and C++ | Commonly associated with Python |
9. What is an API?
API stands for Application Programming Interface. It allows two different software applications to communicate and exchange information.
For example, a weather application can use a weather API to retrieve weather information from an external server.
10. What is Git and Why is it Used?
Git is a version control system used to track changes in source code. It helps developers manage project versions and collaborate with other team members.
Advantages of Git:
- Tracks changes in source code.
- Maintains different versions of a project.
- Supports teamwork and collaboration.
- Helps restore previous versions.
