Wipro Technical Interview Questions for Freshers 2026

Wipro Technical Interview Questions for Freshers 2026

Securing an interview call from Wipro through their Elite National Talent Hunt (NTH) or campus placements is a massive milestone for any fresher. Wipro is one of India’s top IT service giants, and their technical interview is designed to test your foundational knowledge, problem-solving mindset, and trainability.

Unlike product-based companies that focus heavily on advanced Data Structures and Algorithms (DSA), Wipro's technical round for freshers leans heavily into core Computer Science subjects, Object-Oriented Programming (OOPs), and basic database management.

In this guide, we have compiled the most frequently asked technical interview questions at Wipro for the 2026 hiring cycle.

1. Object-Oriented Programming (OOPs)

OOPs is the holy grail of Wipro technical interviews. Whether you code in Java, C++, or Python, you must know these concepts inside out.

Q: What are the four main pillars of OOPs? Explain with real-life examples. Answer:

• Encapsulation: Wrapping data and code into a single unit (like a capsule). Example: A bank account class where variables (balance) are hidden and can only be accessed through specific methods (deposit/withdraw).
• Abstraction: Hiding complex implementation details and showing only the essential features. Example: Driving a car; you know how to use the steering wheel and pedals, but you don't need to know the internal engine combustion process.
• Inheritance: A mechanism where a new class inherits properties and behaviors of an existing class. Example: A 'Dog' class inheriting from an 'Animal' class.
• Polymorphism: The ability of an object to take many forms. Example: A draw() method that draws a circle when called on a Circle object, but a square when called on a Square object.

Q: What is the difference between Overloading and Overriding? Answer:

• Method Overloading (Compile-time Polymorphism): Multiple methods in the same class have the same name but different parameters (type or number of arguments).
• Method Overriding (Run-time Polymorphism): A subclass provides a specific implementation for a method that is already defined in its parent class. The method signature must be exactly the same.

2. Core Java / C++ (Programming Language Basics)

You will be asked to choose a primary language. Java is highly preferred at Wipro.

Q: What is the difference between String, StringBuffer, and StringBuilder in Java? Answer:

• String is immutable. Once created, its value cannot be changed. Every time you concatenate, a new object is created in the memory.
• StringBuffer is mutable and thread-safe (synchronized), meaning it is safe to use in a multi-threaded environment, but it is slower.
• StringBuilder is mutable but not thread-safe. It is faster than StringBuffer and is the preferred choice for single-threaded string manipulations.

Q: Explain the difference between malloc() and calloc() in C/C++. Answer:

• malloc() allocates a single block of requested memory. It does not initialize the memory, meaning it contains garbage values by default.
• calloc() allocates multiple blocks of memory and initializes all bytes to zero.

Q: What are pointers? Why do we use them? Answer: A pointer is a variable that stores the memory address of another variable. They are used for dynamic memory allocation, passing arrays/strings to functions efficiently, and building complex data structures like linked lists and trees.

3. Database Management Systems (DBMS) and SQL

Expect at least 2-3 questions on databases. Writing basic SQL queries on paper or a shared screen is very common.

Q: What is the difference between TRUNCATE, DELETE, and DROP? Answer:

• DELETE: A DML command used to remove specific rows from a table based on a WHERE clause. It can be rolled back.
• TRUNCATE: A DDL command used to delete all rows from a table at once. It cannot be rolled back and is faster than DELETE.
• DROP: A DDL command that deletes the entire table structure along with its data from the database.

Q: Write an SQL query to find the second highest salary from an Employee table. Answer:

SELECT MAX([Salary](/salary/bsc-nursing-salary-india)) FROM Employee 
WHERE Salary < (SELECT MAX(Salary) FROM Employee);

Q: What are ACID properties in a database? Answer: ACID stands for Atomicity (all or nothing), Consistency (data remains valid before and after transaction), Isolation (transactions don't interfere with each other), and Durability (committed transactions persist even after system failure).

4. Software Engineering and SDLC

Since Wipro is a service-based company, they want to know if you understand how software is developed in enterprise environments.

Q: What is the difference between the Waterfall model and Agile methodology? Answer:

• Waterfall is a linear, sequential approach where one phase (e.g., design) must be completed before the next (e.g., coding) begins. It lacks flexibility.
• Agile is an iterative approach where software is developed in small increments (sprints). It welcomes changing requirements and involves continuous client feedback.

Q: What is the difference between testing and debugging? Answer:

• Testing is the process of finding bugs or defects in the software. It is usually done by a QA/Testing team.
• Debugging is the process of locating the exact cause of the bug and fixing it. It is done by developers.

5. Coding Questions (Whiteboarding)

You won't be asked to solve LeetCode Hard problems, but you must be able to write basic logic without an IDE. Practice writing code for:

1. Palindrome Check: Write a program to check if a string or number is a palindrome.
2. Fibonacci Series: Print the Fibonacci series up to N terms (using recursion and iteration).
3. Prime Number Check: Write an optimized code to check if a number is prime.
4. Array Reversal: Reverse an array without using a secondary array (using the two-pointer approach).
5. String Reversal: Reverse a string without using built-in functions.

Final Tips for the Wipro Technical Round

1. Be Honest About What You Don't Know: If you don't know the answer, politely say, "I am currently not aware of this concept, but I am eager to learn." Interviewers appreciate honesty over bluffing.
2. Master Your Final Year Project: You will definitely be asked to explain your major project. Be prepared to discuss your role, the technology stack you used, and the challenges you faced while building it.
3. Think Out Loud: When given a coding problem, don't just sit in silence and write the final answer. Explain your logic to the interviewer as you build the solution.

By solidifying your grasp on these fundamental concepts, you will confidently clear the Wipro technical interview and secure your spot in one of India's leading IT companies.
