Wipro Interview Questions And Answers
Here are some common Wipro interview questions and sample answers you can customise to show your experience and skills:
What are the steps involved in the software development life cycle?
Interviewers ask this question to determine your understanding of the phases of software development. To answer this question effectively, it is important to list and explain every step under the software development life cycle (SDLC) in a clear and succinct manner.
Example: 'SDLC is a process followed within a software organisation to design, build and test software. SDLC stands for software development life cycle. The first stage in SDLC is requirement gathering and analysis. This phase involves communicating with stakeholders, gathering information and understanding all project requirements. This phase also involves a feasibility analysis for the product being developed. The next phase is the design phase, where software architects design a detailed system architecture based on the project requirements. The coding or implementation phase involves translating the software design into source code.
Once the coding phase ends, the software enters the testing phase to ensure that the software is as per customer standards. After several rounds of thorough testing, developers deploy the software to a user acceptance testing environment, and subsequently to the live environment after the customer sign-off. The final stage in SDLC is the maintenance phase, which includes working on issues, fixes and enhancements that occur in the live environment.'

What are the three levels of data abstraction in a database management system?
Data abstraction is an important concept in a database management system (DBMS). This question tests a candidate's understanding of this concept and their approach to transforming complex data structures into simpler ones.
Example: 'Abstraction is a process that helps one hide irrelevant details from the users of a system. There are three levels of abstraction in DBMS. They are physical, logical and view level abstractions. Physical abstraction is the lowest abstraction level and gives us complex details like where and how to store data. Programmers generally work at the logical abstraction level, which describes what data gets stored in the database. View level abstraction is the highest form of abstraction where end-users interact with the system on a graphical user interface level.'

Explain the DROP, TRUNCATE and DELETE commands in SQL
Interviewers at Wipro may ask this question to test your expertise in SQL and the ability to manage a database. You can list down the key differences among these three commands to answer this question satisfactorily.
Example: 'DROP command deletes an entire view, table or database while TRUNCATE deletes all the rows of a particular table. The DELETE command can delete one or more table rows based on specific conditions. Hence, while the DROP command deletes the entire table structure, TRUNCATE and DELETE retain the original table structure. You cannot roll back data in case of DROP and TRUNCATE but you can roll back data after a DELETE command.'

What is the difference between error and exception in Java?
This question tests your programming knowledge. Answering this question well can allow you to display your ability to debug and handle exceptions in the code.
Example: 'An error usually occurs because of insufficient system resources. One cannot catch or handle errors using program code. Exceptions occur because of system code, and developers can handle exceptions using try-catch blocks. An error occurs at run-time and thus belongs to the unchecked category. Exceptions can belong to both checked and unchecked categories. StackOverflow and OutOfMemory are examples of errors, while ClassNotFound and IndexOutOfBounds are examples of exceptions.'

What is time slicing in CPU Scheduling? What are its advantages?
Interviewers ask this question to determine a candidate's knowledge of operating systems (OS) concepts. Since software professionals write code that frequently interfaces with other software systems, high-level knowledge of OS can be useful.
Example: 'Time slicing is a CPU scheduling mechanism that lets a task or process execute on the CPU for a predetermined amount of time. CPU scheduling advantages include a fair distribution of CPU resources and an equal prioritisation of processes. Thus, all processes have an equal opportunity to use the CPU.'
What is RAID in project management?
This question tests a candidate's knowledge of common project management tools and practices. Various steps involved in RAID and the benefits of using this technique are important aspects to include in your answer to this question.
Example: 'RAID framework stands for risks, assumptions, issues and dependencies. It helps managers thoroughly analyse the project and helps avoid issues and events that could impact project outcomes. Its first aspect includes analysing and assessing possible risks and developing specific plans to address them. The next aspect is listing down various assumptions in the project. Issues include events that cause an adverse impact on project progress. Dependencies are various activities to address for ensuring the smooth execution of the project.'

Explain the difference between association, aggregation and composition in Java
Interviewers ask this question to test your understanding of the different types of relationships in object-oriented programming. To answer this question, you can define each type of relationship in simple terms and support the definition with a real-life example.
Example: 'An association is a relationship between two classes established through their objects. There are different kinds of associations like one-to-many, one-to-one, many-to-one and many-to-many. There are two forms of association—aggregation and composition—in object-oriented programming. Aggregation is a relationship where a child exists independently of the parent. For example, consider parent class School and child class Students. Delete School class and Students class still exists.
Composition is a relationship where the child completely depends on the parent and cannot exist without it. For example, consider parent class House and child class Room. Room cannot exist if House does not exist.'
Why would you like to join Wipro?
This is a common question put forth by organisations to assess the interest level of the applicant. This question is a good way for recruiters to assess your knowledge about the company and if you have prepared well for the interview. Briefly researching the company, its history, products and services beforehand is a good way to sound knowledgeable and confident during your interview.
Example: 'Wipro stands third among the top IT companies in the country. It has good policies, work culture and potential, and offers a multi-cultural and diverse work environment. The infrastructure and leadership of Wipro are exceptional, making it a great company to work for.'

Why do we hire you?
Interviewers ask this question to identify top skills and strengths in candidates. A convincing answer to this question can help you make the right impression on recruiters in an interview. This question also helps the interviewer determine if you are a good fit for the position for which they are hiring.
Example: 'I am a quick learner who can quickly grasp and learn new things. I enjoy solving problems and can work calmly and efficiently under pressure. I have led teams effectively in the past, and have good delegation and leadership skills. My critical thinking skills help me tackle problems rationally and use my judgement to make the right decisions.'
What are your strengths and weaknesses?
This is a frequent question recruiters ask, especially in the HR interview. Giving the interviewer an honest, genuine and confident answer that highlights your major skills and talents can set the right impression and increase your chances of getting the job. Expressing your weaknesses in a positive manner is equally important while answering this question.
Example: 'I consider my strong work ethic as my biggest asset and strength. I am ready to take on challenging assignments and have always been willing to step in when required. I can easily adapt to different situations at work and do my best to bring the best results to my organisation. As for my weakness, I sometimes have a tendency to overwork. I am working on prioritising things better to ensure that I have enough time for myself outside work, too.'
