Wipro Technical Interviews

After the aptitude test, the candidates who qualify will be invited to an interview round. If you achieve a high score on the online assessment, you’ll be invited to interview. The results get declared around 2 weeks after the exam and the interview gets scheduled 1 week after the results are obtained. The first interview is a technical/functional interview with representatives from Wipro’s business and talent acquisition teams. Depending upon the circumstances, this interview may be held in-person at a Wipro office or conducted virtually.

During a technical interview, which is typically related to the technical knowledge needed for the position you have applied for, your technical talents are assessed. As this is the first time you’ll meet a member of the Wipro recruitment team, seek to convey both your skills and your personality. It is important to showcase your experience, expertise, and knowledge, alongside why you would be a great cultural fit for the company. Your capacity for problem-solving and numerical reasoning will be put to the test by the questions. Along with technical knowledge, interviewers are interested in how candidates approach challenges, organize their thoughts, and demonstrate interpersonal skills like communication (which is vital). Be direct and transparent. 

If you are applying for a technical role, be prepared to answer technical, detail-oriented questions in the interview. You should be able to describe basic computer concepts to the interviewer, such as OOPS, DBMS, CN, and OS. Although you don't need to be an expert in every programming language, you should at least be conversant with an OOP language like Java and a POP language like C. You can also be requested to write code. You'll be questioned about your prior work, including what you accomplished, how you used technology, and how successful it was. Based on your performances in previous rounds, your job profile, and the needs of the organization, the number of technical interviews that will be held will be determined.

Peoples experience with the interview:

Interviewee 1:

I have appeared for “Wipro Elite National Talent Hunt-2021 “After successfully passing the round 1, you get the mail from Wipro Hiring Team to fill the form if you want to appear for technical interview. Once you submit the form, they will schedule your interview probably after 10–12 working days. My interview was conducted via Webex meet and it was just a 15 minutes technical interview.

Interviewer asked the following questions:

Tell me about yourself .

Have you given your 8th semester exams. Did you get your result *Since i didn’t get my result* : Tentatively what are the dates you expect to get it

Any active backlogs or education gap?

What are the languages you ae familiar with *In my case 3 : Java, Python, C++* : Rate yourself in all the 3 languages

*I rated myself 4 in all the languages* So, he asked if I give you a problem then which will the first language you will think your logic to be in. Which language am I more comfortable in and why?

Tell me about your B.tech Project *Since I used Laravel framework in my project* Why did you choose Laravel framework .Was it a group project ? What was your role in it ? What challenges did you face ?

What are other technologies you are aware of ? What are your strengths ?

Why should we hire you ?

So, where are you from ? Are you ready to relocate ?

By this , my interview came to an end and he said Thank You and we will contact you in some time for further details.

My interview went really good but didn’t receive either acceptance or rejection mail for about a month .

Then almost after a month I received a mail from Wipro Hiring Team that Congratulations you are shortlisted for an HR interview, tomorrow is your HR interview at 2:20 pm.

Interviewee 2:

I am one among the second set of students who has to undergo all the long process to clear since I belong to non CS stream. Have been to the college in the morning and the entire process lasted till night. After the results of the aptitude test were announced it was already 4 pm. Then we were asked to have our lunch within half an hour. Next round started at 5:30 pm. Technical interview. The interview lasted for 20 minutes approx. and he asked my favorite subject. Since I am from EC I chose digital electronics (easier than any other). He asked about logic gates, combinational and sequential circuits to test my conceptual knowledge(since I am preparing for GATE it was easy for me) followed by questions on my mini project and presentation since it was based on IOT. Next questions are from C programming. I didn't answer some of the questions from C. Next he checked my logical ability through a question to which I answered fortunately. Selected for the next round. HR.

Interviewee 3:

The next round after the online aptitude exam, was  the technical interview. The HR asked me from which domain she can ask me questions. As I was a non-IT student, I told her to ask me anything related to electronics. Then she had a look at my resume and started asking questions from that. I have mentioned various technical presentations in my resume. I started explaining that. And then I explained her about my project too. She was amazed on hearing that idea. She congratulated me for the thought. Then we had some general discussion. It lasted for around 15 minutes.

Sample questions:

1)What is inheritance, abstraction, polymorphism, encapsulation?

Answer: 

Inheritance: Inheritance is the methodology of using properties and methods of an already existing class in a new class. The existing class is the parent or superclass while the new class is the child or subclass. The developer does not have to write the code from the beginning. Instead, he can use the already existing code and develop the rest. Therefore, inheritance allows code reusability.

Abstraction: Abstraction is the methodology of hiding the internal details and displaying only the functionality to the users. In other words, the user or the external world does not see the internal implementation details. 

Polymorphism: It is the concept that you can access objects of different types through the same interface. Each type can provide its own independent implementation of this interface.

Encapsulation: Encapsulation is defined as the wrapping up of data under a single unit. It is the mechanism that binds together code and the data it manipulates. Another way to think about encapsulation is, that it is a protective shield that prevents the data from being accessed by the code outside this shield.  

2) Difference between method overriding and method overloading.

Answer: 

1), Method overloading is used to increase the readability of the program while method overriding is used to provide the specific implementation of the method that is already provided by its super class.

2), Method overloading is performed within class while method overriding occurs in two classes that have IS-A (inheritance) relationship.

3), In case of method overloading, parameter must be different while in case of method overriding, parameter must be same.

4), Method overloading is the example of compile time polymorphism while method overriding is the example of run time polymorphism.

5), Method overloading can't be performed by changing return type of the method only. Return type can be same or different in method overloading. But you must have to change the parameter while in method overriding Return type must be same or covariant in method overriding.

3)What is DBMS?

Answer: A database management system (or DBMS) is essentially nothing more than a computerized data-keeping system. Users of the system are given facilities to perform several kinds of operations on such a system for either manipulation of the data in the database or the management of the database structure itself.

4) What makes a macro faster than a function in the C programming language?

Answer: Macros are sections of code in a program that have been given a name. The compiler substitutes this name with the real piece of code whenever it encounters this name. To define a macro, use the '#define' directive. Macros can be defined either before or within the main method. Macros are pre-processed, which implies that all macros are processed before the code is compiled, and functions are processed after the code is compiled.

5)What are the differences between an object-oriented programming language and an object-based programming language?

Answer: The following are the main differences between object-oriented and object-based languages.

Object-oriented languages adhere to all Object-Oriented Programming concepts, but object-based languages do not adhere to all Object-Oriented Programming concepts such as inheritance, polymorphism, etc.

Object-oriented languages lack built-in objects, but object-based languages do. For example, JavaScript contains a built-in window object.

Java, C#, Smalltalk, and others are examples of object-oriented programming languages while JavaScript, VBScript, and others are examples of object-based languages.

6) How can you make a request for garbage collection in Java?

Answer: There are two ways to ask the JVM to run the Garbage Collection.

1. The garbage collection methods are available in the Runtime class given by Java. For any Java program code, the Runtime class is a singleton. A singleton instance of the Runtime class is returned by the function getRuntime(). This instance of Runtime can be used to call the gc() function to request garbage collection.
2. Request the JVM to perform GC using the System class System.gc() function.

7) Explain precondition and postcondition to a member function in the context of C++ programming language.

Answer: A precondition is a condition that must be met before a member function may be called. If preconditions are never false, a class is appropriately used. If a precondition fails to hold, the following function is not executed. For example, before inserting an element into a stack, we call the isfull() to check if the stack is full or not. Here, the isfull() is an example of a precondition.

A post-condition is a condition that must be true when a member function is exited if the precondition was true when the function was entered. For a code to be correctly implemented, the post-conditions must never be false for example, we know that isempty() must always hold after placing an element onto the stack. This is a push operation post-condition.

Good luck and ALL THE BEST!!!!! Never Give UP!!!
