Wipro Interview Questions

Q1. Tell me about yourself.

Give a 60–90 second summary: education, key skills/projects relevant to IT, and why you want to begin your career at Wipro, ending with enthusiasm.

Q2. Write a program to find the factorial of a number.

Iteratively multiply 1..n, or recursively return n * factorial(n-1) with base case factorial(0)=1. Watch for overflow at large n (use long/BigInteger).

Q3. What is the difference between structure and union in C?

A structure allocates separate memory for every member (total = sum of sizes); a union shares one memory block sized to its largest member, so only one member holds a valid value at a time.

Q4. What is a constructor? What are its types?

A constructor initialises an object when it's created. Types: default (no args), parameterised, and copy constructor. It has the class name and no return type.

Q5. Explain the difference between GET and POST.

GET appends data to the URL, is cacheable, has length limits and is for retrieval. POST sends data in the body, isn't cached, has no size limit and is for creating/modifying data securely.

Q6. What is indexing in a database?

An index is a data structure (often a B-tree) that speeds up lookups on a column at the cost of extra storage and slower writes. It's like a book's index — you jump to the data instead of scanning every row.

Q7. What is the difference between overloading and overriding?

Overloading: same method name, different parameters, resolved at compile time (static polymorphism). Overriding: subclass redefines a superclass method with the same signature, resolved at runtime (dynamic polymorphism).

Q8. Find the largest element in an array.

Initialise max to the first element, iterate once comparing each element and updating max. O(n) time, O(1) space.

Q9. What is a NULL value in SQL?

NULL means the value is unknown or missing — it's not zero or an empty string. Comparisons with NULL use IS NULL / IS NOT NULL, since NULL = NULL is not TRUE.

Q10. What is recursion? Give a use case.

Recursion is a function calling itself with a smaller input until a base case. Used in factorials, Fibonacci, tree/graph traversal, and divide-and-conquer algorithms like merge sort.

Q11. Why do you want to join Wipro?

Reference Wipro's global presence, values-driven culture, strong fresher training, and diverse project exposure, connected to your goal of a solid engineering foundation.

Q12. Are you willing to sign the service agreement and relocate?

Yes — confirm both clearly. A service agreement and relocation flexibility are standard for Wipro fresher offers.

Q13. What is DBMS vs RDBMS?

A DBMS stores data (possibly as files) without necessarily enforcing relationships; an RDBMS stores data in related tables with keys, enforces ACID and relationships, and supports SQL (e.g. MySQL, Oracle).

Q14. What are your career goals?

Show short-term intent (master engineering fundamentals and deliver on projects) and a realistic longer-term direction (grow into a specialist or lead), aligned with staying and growing at Wipro.

Q15. Do you have any questions for us?

Yes — ask about the training program, the technologies freshers work with, or how Wipro supports upskilling. It signals engagement.

Elite NLTH (National Level Talent Hunt) is Wipro's national fresher hiring test covering aptitude, English, essay and coding, followed by interviews.

Yes, Wipro fresher offers typically include a service agreement/bond — be prepared to confirm your willingness in the HR round.

Usually C, C++, Java or Python for the coding round — pick the one you're strongest in.
