NTT DATA Interview Process

The interview process at NTT DATA can vary depending on the position you are applying for. However, most positions will require at least one face-to-face interview. For some positions, like software developer or data analyst, you may be asked to complete a technical interview. This could include questions about your experience with specific programming languages or tools. Other positions, like project manager or finance manager, may require you to answer questions about your experience in the field. Overall, the interview process is relatively standard, but it is important to be prepared for any type of question that may come up.

1. What are your long term career goals?

This question is an opportunity to show the interviewer that you are motivated and have a plan for your career. Your answer should include what motivates you, how you will achieve your goals and what steps you’ve already taken toward achieving them.

Example: “I want to become a senior IT consultant in five years. I am currently working on my certification as a Certified Information Systems Auditor so that I can be ready to take on more complex projects when I’m ready to apply for this role. I also hope to one day open my own consulting firm.”

2. How would you rate your coding skills?

This question is a great way for the interviewer to assess your technical skills and determine if you’re qualified for the position. If you have experience coding, share that information with the interviewer. If you don’t have any coding experience, explain why you would be able to learn this skill quickly.

Example: “I’ve been coding since I was in high school, so I’m quite comfortable with it. In my last job, I worked on several projects where I had to code, including creating databases and writing scripts. I also completed an online course on Python programming, which helped me understand how to write codes.”

3. Are you comfortable working in a fast-paced environment?

NTT DATA is a fast-paced company that requires employees to be flexible and adaptable. Your answer should show the interviewer you can work in this type of environment.

Example: “I am comfortable working in a fast-paced environment, as I have worked for companies where deadlines are tight. In my last job, I was part of a team that had to meet tight deadlines on projects. We were able to complete all our tasks within the deadline because we communicated well with each other and prioritized our tasks effectively.”

4. Why do you want to work for NTT DATA?

This question is a great way for the interviewer to learn more about your interest in their company. They want to know what you like about NTT DATA and why you’re excited to work there. When preparing for this question, make sure to highlight specific aspects of the company that appeal to you.

Example: “I’ve always been impressed with NTT DATA’s reputation as an IT leader. I’m also very interested in working for a global company because it would give me the opportunity to expand my skills and experience. Additionally, I love how NTT DATA focuses on innovation and customer service. These are two things that are important to me.”

5. Explain the difference between abstract classes and interfaces.

This question tests your knowledge of object-oriented programming. It also helps the interviewer determine if you have a strong foundation in OOP and can apply it to real-world situations.

Example: “In general, interfaces are used for defining methods that other classes implement. Abstract classes are similar to interfaces but they contain abstract methods that must be implemented by subclasses. This is useful when you want to create multiple objects with common functionality. For example, I once worked on a project where we needed to create multiple types of vehicles that all had different functions. We created an abstract class for vehicle functionality and then subclassed it to create specific vehicles.”

6. If an application does not have enough memory, what will happen during its execution?

This question is a basic technical test to see if you understand the basics of programming. It also tests your ability to troubleshoot and solve problems. Your answer should show that you know how to fix this issue.

Example: “If an application does not have enough memory, it will crash or freeze during execution. This can be caused by insufficient memory in the computer’s RAM or hard drive space. If there is no more room for data in the cache, the system has to write data to the hard disk, which takes longer than writing to the RAM. To avoid this problem, I would check the available memory on the computer and increase it as needed.”

7. Do you have experience leading technical teams?

This question can help the interviewer determine if you have experience managing a team of IT professionals. If you do, share your leadership style and how it helped your team succeed. If you don’t have direct management experience, you can talk about your ability to work with others and collaborate on projects.

Example: “In my last role as an IT consultant, I led a team of five other consultants who specialized in different areas of technology. We met regularly to discuss our clients’ needs and develop strategies for meeting those needs. As a result, we were able to provide high-quality solutions that exceeded client expectations.”

8. What is your least favorite programming language and why?

This question is a great way to see how you handle criticism. It also shows the interviewer what your programming skills are like and whether or not they match up with the job requirements. When answering this question, be honest about why you don’t enjoy that language but emphasize any positive aspects of it.

Example: “My least favorite programming language would have to be Java because I find it very verbose. While there are many benefits to using Java, such as its object-oriented nature and portability, I prefer languages that are more concise. However, I am quite proficient in Java and can use it when needed.”

9. Can you tell me about a time when you had to solve a problem that was not straightforward. How did you approach the problem?

This question is an opportunity to show your problem-solving skills. When answering this question, it can be helpful to describe a specific situation and how you used critical thinking to solve the issue.

Example: “At my previous job, I was working on a project that required me to create a new database for one of our clients. The client wanted to have several different reports in their system, but they didn’t want to pay extra for them. So, I had to figure out a way to make all of the reports available without having to add more money to the budget. After some research, I found a way to save the company money by using existing data.”

10. Which version control systems have you used?

This question is a good way to assess your technical knowledge and experience with different types of systems. You can list the version control system you’ve used, what type of project it was for and how well you performed in that role.

Example: “I have worked with three major version control systems—GitHub, Bitbucket and Mercurial. I started out using GitHub because it’s one of the most popular systems available today. However, as my career progressed, I found myself working on projects where GitLab would be more beneficial. For example, when I was working on an open-source software development project, I found GitLab to be much better than GitHub due to its ability to support multiple programming languages.”

11. Tell us about a project where you made a significant contribution.

This question is a great way to show your interviewer that you are capable of taking on challenging projects and delivering results. When answering this question, it can be helpful to describe the project in detail and highlight what made it significant for you or your team.

Example: “At my previous job, I was tasked with creating an IT infrastructure for a new company. This included setting up servers, computers, printers and other devices. It also involved installing software and configuring security measures. The project took several months to complete, but I am proud of the work we did because it helped the company save money by eliminating the need for outside IT services.”

12. Describe how inheritance works in Java.

This question tests your knowledge of Java. It also shows the interviewer how you apply that knowledge to solve problems in a technical environment.

Example: “Inheritance is one of the most important concepts in object-oriented programming, and it’s used to create new classes from existing ones. In Java, inheritance occurs when a class inherits all the properties of another class. This means that any changes made to the parent class are automatically applied to its child class. For example, if I have a class called Dog with two subclasses, Labrador and Poodle, then both Labrador and Poodle inherit all the properties of the Dog class.”

13. Give us an example of a project where you worked with others who were less experienced than you. How did you interact with them?

This question is a great way to show your leadership skills and ability to work with others. When answering, it can be helpful to mention how you helped the other team members learn or grow their skills.

Example: “In my last role as an IT consultant, I worked on a project where I was managing a group of five junior-level consultants. The company had hired them because they were looking for more senior level employees, but they didn’t have enough budget to hire anyone else. My job was to help train these new hires so that they could complete tasks independently.

I found that one of the best ways to do this was by creating checklists and providing detailed instructions. This allowed me to delegate tasks while still making sure everyone understood what they needed to do.”

14. Have you ever consulted before?

This question is a great way to show your experience and knowledge in the field. If you have, explain what kind of consulting you did and how it helped your previous employer. If you haven’t done any consulting before, you can talk about other ways you’ve helped clients or customers with their IT needs.

Example: “I’ve worked as an IT consultant for many years now. I started out working at a small company where I was responsible for helping my team members solve problems and troubleshoot issues. As I gained more experience, I began doing some basic consulting work for smaller companies that didn’t have full-time IT staffs.”

15. What data structures do you know?

This question is a basic technical test to see if you have the necessary skills for this role. You should list out all of the data structures that you know and give an example of when you used them in your previous roles.

Example: “I am familiar with many different types of data structures, including linked lists, stacks, queues, trees, heaps and graphs. In my last position as a senior systems engineer, I was tasked with creating a new database system for a client. The company wanted to use a graph structure because it would allow them to easily navigate between nodes and sub-nodes. Using my knowledge of data structures, I created a new database system using a graph structure.”

16. What are some benefits of using object-oriented languages compared to procedural languages?

This question is a basic technical interview question that tests your knowledge of programming languages. You can use this opportunity to show the interviewer you have experience with different types of programming languages and their benefits.

Example: “Procedural languages are easier to learn than object-oriented languages, but they’re also less flexible. Object-oriented languages allow for more flexibility because they support objects, which are reusable code units. This means I can create new applications by combining existing objects instead of having to write all the code from scratch.”

17. What are your strengths as a developer?

This question allows you to highlight your skills and abilities as a developer. You can discuss the technical skills that are relevant to this role, but also consider discussing soft skills like communication or teamwork.

Example: “I have excellent problem-solving skills, which I use to find solutions to complex issues. My ability to work independently is another strength of mine because it allows me to complete projects on time. I am also highly organized, which helps me stay focused on my tasks. Another strength of mine is my attention to detail, which ensures that all of my code is error-free.”

18. When should you use polymorphism?

Polymorphism is a programming concept that allows you to use the same code for different types of objects. This question helps interviewers understand your knowledge of object-oriented programming and how it can be used in real-world situations. Use examples from previous work or school projects to show how polymorphism helped you complete tasks more efficiently.

Example: “Polymorphism is useful when working with multiple instances of the same type of object, such as an employee who has multiple roles within their company. In my last role, I was tasked with creating a system that would allow employees to view their paychecks online. Using polymorphism, I created a base class for all employees, which allowed me to create subclasses for each employee’s unique role. This saved time by allowing me to write less code.”

19. We have many projects going on at once, which requires our developers to be organized. Are you prepared to manage multiple deadlines?

This question can help the interviewer understand how you plan your time and manage multiple projects. Showcase your ability to prioritize tasks, meet deadlines and communicate with team members about project status.

Example: “I have experience managing multiple projects at once. I use a calendar app on my phone to keep track of all my deadlines and due dates for each project. This helps me stay organized and ensures that I’m meeting all my client’s needs in a timely manner.”

20. What is the best way to make sure that software is secure from hackers?

This question is a great way to show your knowledge of cybersecurity and how you can apply it in the workplace. When answering this question, make sure that you explain what steps you would take to ensure software is secure from hackers.

Example: “The best way to keep software secure from hackers is by using security testing tools. These tools allow me to test for vulnerabilities within software before it’s released to customers. This allows me to find any issues with the software so I can fix them before they become a problem.”
