Wipro Technical Interview Questions for Non-IT Candidates
Question 1:- What are the steps involved in designing?
Answer:-
Requirements, Design, Coding, Testing, Re-coding and design, Development, and Maintenance are all steps involved in designing.
Question 2:- Is XML case sensitive?
Answer:-
When uppercase and lowercase letters are processed differently in XML, it is case-sensitive. The case is important when it comes to element type names, attribute names, attribute values, all generic and parameter entity names, and data content (text).
Question 3:- What is a Null object?
Answer:-
It’s a class object whose sole function is to signify the absence of a genuine object of that class. A return result from a member function that is expected to return an object with the specified properties but cannot locate one is the typical usage for a null object.
Question 4:- Write a code for prime numbers.
Question 5:- What is the difference between UNIQUE and PRIMARY KEY constraints?
Answer:-
A UNIQUE constraint is identical to a PRIMARY key, except that each table can contain many UNIQUE constraints. UNIQUE constraints, unlike PRIMARY keys, may take NULL only once. If the constraint is established over many fields, each field can permit NULL and have some values as long as the combined values are unique.
Question 6:- What is an IP address?
Answer:-
A numerical label provided to each device (e.g., computer, printer) participating in a computer network that utilizes the Internet Protocol for communication is known as an Internet Protocol address (IP address). An IP address has two main functions: identifying the host or network interface and addressing the location.
Question 7:- What are the differences between an object-oriented programming language and an object-based programming language?
Answer:-
All Object Oriented Programming ideas are adhered to by object-oriented languages, however not all Object Oriented Programming concepts are adhered to by object-based languages, such as inheritance, polymorphism, and so on.
Object-oriented languages do not have built-in objects, but object-based languages do. Object-oriented programming languages include Java, C#, Smalltalk, and others, whereas object-based languages include JavaScript, VBScript, and others.
Question 8:- What is the difference between interface and multiple interface?
Answer:-
An abstract class and an interface are both sorts of computer objects that allow a programmer to informally describe one type of object as if it were a different type while keeping all of the item’s original features. Java is the most well-known of the computer languages that employ one or both of these notions. There are many parallels between abstract classes and interfaces, but there are also substantial variations in structure, syntax, and usage.
Question 9:- When do you use SQL Profiler?
Answer:-
The SQL Profiler software allows us to track SQL Server connections and determine actions such as which SQL Scripts are executing, unsuccessful tasks, and so on.
Question 10:- Write a program for factorial of a number
Wipro Technical Interview Questions for IT Candidates
Question 1:- What is stack unwinding?
Answer:-
The practice of removing function entries from the function call stack during runtime is known as stack unwinding. Stack Unwinding is frequently related to Exception Handling. When a C++ exception occurs, the function call stack is searched linearly for the exception handler, and all entries preceding the function with the exception handler are removed. Stack unwinding is necessary if the exception is not handled in the same function (where it is thrown).
Question 2:- What is DOM?
Answer:-
The Document Object Model (DOM) is a language-independent and cross-platform standard for describing and interacting with objects in HTML, XHTML, and XML texts. Using methods on the objects, you may address and modify objects in the DOM tree. The application programming interface of a DOM specifies its public interface (API).
Question 3:- Write a code for Bubble sort.
Question 4:- What is the gc() method?
Answer:-
This gc() function is used to call Garbage Collector. Both system and runtime classes contain it. When an item is no longer in use, it immediately releases the memory.
Question 5:- What is meant by statically-typed language?
Answer:-
Java is a type-safe programming language. All variables must be defined before they may be utilized in a statically-typed language.
Question 6:- If a class is declared without any access modifiers, where may the class be accessed?
Answer:-
Package access refers to a class that is specified without any access modifiers. This implies that only other classes and interfaces specified inside the same package can access the class.
Question 7:- Explain free() vs delete () in C++.
Answer:-
Both delete() and free() are used to deallocate memory dynamically.
- The term “delete” is a C++ keyword, but the free() function is a C library function that can also be used in C++.
- The free() function deletes a pointer allocated using the malloc(), calloc(), or realloc() methods or a NULL pointer, whereas the delete operator deletes a pointer created with the new operator or a NULL pointer.
- When the delete operator in C++ eliminates the allocated memory, it calls the class’s destructor, but the free() method does not; it just frees the memory from the heap.
Question 8:- What is Blockchain?
Answer:-
Blockchain is a method of storing data that makes it difficult or impossible to manipulate, hack, or defraud the system. A blockchain is a digital log of transactions that is copied and distributed throughout the blockchain’s complete network of computer systems.
Question 9:- Write a program for finding the kth node from the end of the linked list.
Question 10:- What are the advantages of passing this into a method instead of the current class object itself?
Answer:-
Because this relates to the current class object, it must be comparable to that object. There are two major advantages to giving this into a method rather than the current class object:
- this is a final variable. As a result, this cannot be given to any new value, whereas the current class object may not be final and can be altered.
- In the synchronized block, ‘this’ can be utilized.

Question 1:- Tell me about yourself.
Answer:-
I stumbled upon your job description as a recent graduate. According to my understanding, the role requires a calm individual who is eager to take on new challenges. I feel I am an excellent candidate for this role. I learned programming on my own as a Mechanical Engineering student. I’ve created projects that you can discover on my Github, and I’m always learning new skills. In my engineering class, I was an active part of the student body and served as a liaison between students and instructors. Perhaps my greatest skill is that I never back down from a challenge and always approach an issue square in the face.

Question 2:- What are your strengths and weaknesses?
Answer:-
It has been said that my criticisms can be harsh or severe at times. Giving constructive feedback might assist the other person in improving their abilities or performance. So, in recent times, I’ve been attempting to filter my criticism and use words that are encouraging and helpful rather than harsh or judgmental. This method has greatly aided me in gaining trust, respect, and building stronger professional connections.

Question 5:- How do you adapt to change?
Answer:-
It is critical for us as individuals to be able to adapt and operate in response to changing circumstances. I was requested to move to computer software that would handle the work for me at my prior employment, where I had started off doing a lot of manual data input. It was difficult for me to adjust to the program as a non-technical person. I had one of my coworkers assist me in understanding the task, and I also conducted my own study on the technology in order to be able to work with it and provide decent results.
