Technical Interview Questions for Freshers in IT Jobs 2026: Important Questions and Answers
Getting your first IT job is an important step in building a career in the technology industry. For freshers, technical interviews can include questions about programming languages, databases, computer fundamentals, web technologies and problem-solving skills.
Companies generally want to understand whether candidates have strong basic knowledge and can apply technical concepts to practical situations. Preparing commonly asked technical interview questions can help students and recent graduates approach interviews with greater confidence.
This guide covers important technical interview questions for freshers in IT jobs, practical coding examples and preparation tips for different entry-level roles.
Top Technical Interview Questions and Answers for IT Freshers
- What is the difference between C and Python?
C is a procedural programming language that requires more manual control over memory. Python is a high-level programming language known for its readable syntax and is commonly used in automation, web development and data science.
- What are the four principles of OOP?
Object-Oriented Programming is based on four important principles:
- Encapsulation: Combining data and methods within a class.
- Inheritance: Allowing one class to reuse another class’s properties.
- Polymorphism: Using one interface for different implementations.
- Abstraction: Hiding unnecessary implementation details.
- What is the difference between a primary key and a foreign key?
A primary key uniquely identifies each record in a database table. A foreign key connects one table with another by referring to a key in the related table.
- What is the difference between an array and a linked list?
An array stores elements in indexed positions, while a linked list stores elements as connected nodes. Arrays allow direct index-based access, whereas linked lists require traversal to reach a particular node.
- What is an API?
An API allows two software applications to communicate. For example, a weather application can use an API to retrieve weather information from an external service.
- What is the difference between frontend and backend development?
Frontend development focuses on the user interface using technologies such as HTML, CSS and JavaScript. Backend development handles server-side operations, application logic and database communication.
Practical Coding Questions for Freshers
Interviewers may ask candidates to write small programs to understand their logical thinking and programming fundamentals.
Example 1: Reverse a String in Python
text = “Hello”
reversed_text = text[::-1]
print(reversed_text)
Output: olleH
Example 2: Check Whether a Number Is Even or Odd
num = 10
if num % 2 == 0:
print(“Even”)
else:
print(“Odd”)
Output: Even
Candidates should understand how these programs work instead of memorising code.
Important IT Interview Topics by Job Role
Different IT positions require different technical knowledge. Freshers should prepare according to the position they want to apply for.
| IT Job Role | Topics to Prepare |
| Software Developer | Programming, OOP, DSA |
| Web Developer | HTML, CSS, JavaScript |
| Data Analyst | SQL, Excel, Python |
| Java Developer | Core Java, OOP, Collections |
| Python Developer | Python, Functions, Data Structures |
| IT Support | Operating Systems, Networking |
Project-Based Questions Asked in IT Interviews
Academic projects are important for freshers because they provide an opportunity to demonstrate practical knowledge.
Prepare answers to these questions:
- Explain your final-year project and its main objective.
- Which programming languages and tools did you use?
- What technical challenges did you face?
- How did you solve problems during development?
- What improvements would you make to your project?
Explain your actual contribution clearly. Do not claim experience or technical skills that you cannot demonstrate.
How to Prepare for an IT Technical Interview in 2026?
Follow these preparation steps:
- Revise programming fundamentals and practise basic coding problems.
- Learn SQL queries, database concepts and OOP principles.
- Prepare your academic projects with clear technical explanations.
- Practise explaining solutions instead of only memorising definitions.
- Research the company and understand the job description.
- Participate in mock interviews to improve communication.
Students can also explore learning resources through SWAYAM and career opportunities through the National Career Service.
