How the Wipro interview usually goes
Based on what candidates commonly report. The process changes by year, role and campus, so always check the official Wipro careers page and your drive's notification.
- 1
Online assessment
Commonly reported to include aptitude, verbal or written communication (sometimes an essay) and coding. Wipro has run national talent hunt drives (such as Elite NTH) for freshers; check the current drive's details.
- 2
Technical interview
Programming basics in your chosen language, your project, OOP, DBMS and SQL, and some OS or networking questions, sometimes with a short program.
- 3
HR interview
Background, relocation and shifts, and why Wipro. Sometimes combined with the technical round.
Technical questions freshers are commonly asked
Wipro technical interviews for freshers usually stay on fundamentals: your project, one programming language, OOP, DBMS and SQL, and some OS and networking basics, plus a short program to write or explain. Clear, confident communication counts as much as depth.
- Q1.
Explain your final-year (or best) project.
Cover the problem, your own part, the tech stack and why you chose it, one hard bug or decision, and what you would improve. Expect follow-ups on anything you name, so only list what you can defend.
- Q2.
What are the four pillars of OOP?
Encapsulation (keeping data and the methods that use it together, and hiding internal state), abstraction (exposing what an object does, not how), inheritance (a class reusing and extending another) and polymorphism (one interface, many forms). Give a small example in the language you know best.
- Q3.
What is the difference between method overloading and overriding?
Overloading is the same method name with different parameter lists, usually in the same class, and is resolved at compile time. Overriding is a subclass redefining a parent method with the same signature, resolved at runtime (runtime polymorphism).
- Q4.
Abstract class vs interface: when would you use each?
An abstract class can hold fields, constructors and both abstract and concrete methods, and (in Java) a class can extend only one. An interface is a contract a class can implement many of; since Java 8 it can have default and static methods but no instance state. Use an abstract class for a shared base, an interface for a capability.
- Q5.
What is a pointer? What is the difference between malloc() and calloc()?
A pointer stores the memory address of another variable. malloc(size) allocates a block without initialising it; calloc(count, size) allocates space for count elements and sets every byte to zero. Memory from both must be released with free().
- Q6.
What is the difference between a primary key and a foreign key?
A primary key uniquely identifies each row and cannot be NULL; a table has one. A foreign key is a column that refers to a primary (or unique) key in another table, enforcing referential integrity; it can repeat and, unless declared NOT NULL, can be NULL.
SQL basics - Q7.
Explain the types of SQL joins.
INNER JOIN returns rows that match in both tables; LEFT JOIN returns every row of the left table plus matches (NULLs where none); RIGHT JOIN is the mirror; FULL OUTER JOIN returns all rows from both. A self join joins a table to itself, such as employees to their managers.
Joins explained - Q8.
Write a SQL query to find the second-highest salary.
Take the maximum salary below the overall maximum. With window functions, DENSE_RANK() handles ties and generalises to the Nth highest.
Subqueries & CTEsSELECT MAX(salary) FROM employees WHERE salary < (SELECT MAX(salary) FROM employees); - Q9.
What is normalisation? Explain 1NF, 2NF and 3NF.
Normalisation organises tables to reduce duplicate data and update anomalies. 1NF: every column holds atomic values, no repeating groups. 2NF: 1NF and no non-key column depends on only part of a composite key. 3NF: 2NF and no non-key column depends on another non-key column (no transitive dependency).
- Q10.
What is the difference between a process and a thread?
A process is a running program with its own memory space. Threads run inside a process and share its memory (code, heap) while each has its own stack and registers, so they are cheaper to create and switch, but shared data needs synchronisation.
Processes vs threads - Q11.
What is a deadlock, and how can it be prevented?
A deadlock is when two or more processes each wait forever for a resource the other holds. It needs four conditions together: mutual exclusion, hold and wait, no preemption and circular wait. Break any one, for example by always acquiring locks in the same order.
Deadlocks - Q12.
What is the difference between TCP and UDP?
TCP is connection-oriented and reliable: it delivers data in order, retransmits lost packets and controls flow (web pages, email, file transfer). UDP is connectionless with no delivery guarantee but lower overhead (video calls, online games, DNS lookups).
TCP vs UDP - Q13.
Name the layers of the OSI model.
Physical, Data Link, Network, Transport, Session, Presentation and Application. The TCP/IP model used in practice groups them into four layers: Link, Internet, Transport and Application.
OSI & TCP/IP models - Q14.
Reverse a string without using a built-in reverse function.
Use two pointers at the start and end, swap the characters and move both inward until they meet: O(n) time. In languages with immutable strings (Java, Python) convert to a character array or list first.
Two pointers from both ends - Q15.
Check whether a string (or number) is a palindrome.
Compare characters from both ends moving inward; stop at the first mismatch. For a number, reverse its digits and compare with the original. Ask whether case, spaces and punctuation should be ignored.
Two pointers from both ends - Q16.
Write a program to check whether a number is prime.
Numbers below 2 are not prime. Otherwise check divisibility only from 2 up to the square root of n, because any factor larger than the root pairs with one smaller than it. That makes it O(√n).
- Q17.
Print the Fibonacci series, or find the factorial of a number, iteratively and recursively.
Know both versions and their trade-offs: the recursive version needs a base case and uses stack space, and naive recursive Fibonacci is exponential because it recomputes values. A loop (or memoization) makes Fibonacci O(n).
Recursion basics
Wipro HR interview questions
- 1.
Tell me about yourself.
60 to 90 seconds: your degree, one or two projects or skills that fit the role, and what you want next. Don't read out your resume.
Tell me about yourself - 2.
Why should we hire you?
Match two or three of your strengths to the role, each backed by proof such as a project, an internship or a result.
- 3.
What are your strengths and weaknesses?
Pick a real strength with an example, and a real but non-critical weakness along with what you are doing to improve it.
- 4.
Why Wipro?
Point to something concrete: a service line or technology Wipro works in, its training for freshers, or the kind of client work you want to do.
- 5.
Are you willing to relocate and work in shifts?
Answer honestly. Services companies place freshers on projects in different cities and time zones; if you have a genuine constraint, say so politely.
- 6.
Where do you see yourself in five years?
Talk about growing your skills and responsibility in a way that could plausibly happen at this company, not about leaving it.
- 7.
Tell me about a challenge you faced and how you handled it.
Use STAR: the situation, your task, the actions you took and the result, with the focus on what you did.
The STAR method - 8.
Tell me about a time you disagreed with a teammate.
Show that you listened, argued with facts and kept the team moving; end with what you learned.
Conflict & teamwork - 9.
Your branch isn't computer science. Why IT?
Common for ECE, EEE and mechanical students. Show genuine interest with evidence: courses you took, programs or projects you built, and what you enjoy about software.
- 10.
Do you have any questions for us?
Always ask one or two, for example about training, the team you would join, or what a good first year looks like.
Questions to ask the interviewer
How to prepare for the Wipro interview
- 1.
Clear the online test first
The online assessment comes first; practise writing a short, well-structured essay as well as aptitude and coding. Practise aptitude a little every day with timed quizzes: percentages, profit and loss, time and work, number series and seating arrangements come up often.
Aptitude practice - 2.
Make practice a daily habit
Five questions a day adds up. The Daily Quiz takes about three minutes and needs no login.
Daily Quiz - 3.
Revise core CS
OOP, DBMS and SQL, operating systems and networking basics. Aim to explain each concept in two or three sentences with an example.
Study notes - 4.
Know your project inside out
Your role, the tech stack and why, the database design, one problem you solved. Most fresher interviews spend a lot of time here.
- 5.
Write small programs by hand
Strings, arrays and number programs (reverse, palindrome, prime, Fibonacci) in one language you know well, without an IDE, then trace them with an example.
- 6.
Practise speaking out loud
Rehearse "tell me about yourself" and your project explanation. A Wipro-style mock interview with Sam is a safe place to practise.

Frequently asked questions
How many rounds are there in the Wipro interview for freshers?
Commonly an online assessment, then a technical interview and an HR interview (sometimes combined). The process differs by drive, so read the official Wipro careers page and the drive notification.
Does Wipro ask coding questions in the interview?
Often a short program, such as reversing a string, checking a palindrome or prime, or a simple array task, plus questions about the language you know. The online assessment commonly has a coding section too.
Which programming language should I use in the Wipro interview?
Use the language you know best and listed on your resume. C, C++, Java and Python are all common; what matters is writing correct programs and explaining them clearly.
