Interview Questions & Answers for Software Engineer – Java, Angular at NielsenIQ, (0–3 Years Experience)
Q1. Tell me about yourself.
Answer:
I’m a computer science graduate with a strong interest in software development. I have hands-on experience in building web applications using Java, Spring Boot, and Angular. During my academics and internships, I’ve worked on several mini-projects and personal projects that helped me understand the full software development life cycle. I enjoy learning new technologies and improving my coding skills through online platforms like GitHub and HackerRank. I’m excited about the opportunity to work with NielsenIQ because I want to be part of a global team that is using modern technologies to solve real business problems.
Q2. What is Spring Boot and why is it used?
Answer:
Spring Boot is a framework built on top of the Spring Framework. It is used to build standalone, production-grade applications easily. The main benefit of Spring Boot is that it reduces the amount of boilerplate configuration. It provides default settings for many features like logging, database connection, and security, so developers can start building apps faster. It also comes with an embedded server like Tomcat, so we don’t need to deploy our app separately. In short, Spring Boot helps developers focus on writing business logic rather than spending time on configuration.
Q3. Can you explain what a REST API is?
Answer:
A REST API (Representational State Transfer Application Programming Interface) is a way for two software systems to communicate over the internet using standard HTTP methods like GET, POST, PUT, and DELETE. In simple words, it allows one application to talk to another and share data in a structured way, usually using JSON format. For example, if you want to get product data from a server, your application can send a GET request to the API endpoint, and the server responds with the product details. REST APIs are widely used in modern web development because they are simple, flexible, and scalable.
Q4. What is Angular and what are its features?
Answer:
Angular is a front-end web development framework developed by Google. It helps in building dynamic single-page applications (SPAs) with a structured approach. Some of its key features are two-way data binding, which allows automatic synchronization between the model and view, dependency injection, and component-based architecture. Angular also has a powerful CLI (Command Line Interface) that makes it easier to generate components and services. It supports TypeScript, which helps in writing clean and error-free code. Angular is commonly used to build interactive dashboards and user-friendly interfaces.
Q5. What is the difference between GET and POST in APIs?
Answer:
GET and POST are two common HTTP methods used in REST APIs. GET is used to retrieve data from a server. It does not change anything on the server and can be bookmarked or cached. For example, fetching a list of products is done using GET.
On the other hand, POST is used to send data to the server to create or update resources. It is more secure than GET because the data is sent in the request body, not in the URL. For example, when you submit a form to register a user, POST is used. In summary, GET is for reading, and POST is for creating or updating.
Q6. What is CI/CD and why is it important?
Answer:
CI/CD stands for Continuous Integration and Continuous Deployment. These are software development practices that help teams deliver code faster and with fewer errors.
In Continuous Integration, developers frequently push their code to a shared repository. Every time code is pushed, automated tests and builds are run to make sure nothing is broken.
In Continuous Deployment, the tested code is automatically deployed to production or staging environments.
CI/CD helps teams catch bugs early, reduce manual testing, and improve the speed of delivery. For companies like NielsenIQ that build cloud-native apps, CI/CD ensures smooth and reliable software updates.
Q7. How would you handle a situation where your code is not working?
Answer:
If my code is not working, I follow a step-by-step approach to fix it. First, I check the error message or stack trace to understand the problem. Then I use print statements or a debugger to find the exact location of the issue. I also check the logic and data flow in my code. If I still can’t figure it out, I look for similar issues online or in documentation. If needed, I ask my teammates for help. I believe debugging is an important skill, and I try to stay calm and systematic while solving any issue.
Q8. What are the advantages of using cloud platforms like Azure?
Answer:
Cloud platforms like Microsoft Azure provide many advantages for developers and businesses. First, they offer scalability, which means the app can handle more users without crashing. Second, they reduce infrastructure costs because we don’t have to buy physical servers. Third, they offer high availability, data backup, and security features out of the box. Developers can also use Azure services like Azure Functions, Cosmos DB, Azure DevOps, etc., to build and manage applications more efficiently. In companies like NielsenIQ, using Azure helps teams collaborate globally and deploy applications faster.
Q9. Why do you want to work at NielsenIQ?
Answer:
I want to work at NielsenIQ because it is a global leader in consumer insights and uses modern technologies like Java, Angular, Spring Boot, and cloud platforms like Azure. The job role matches my skill set and offers a chance to work on scalable and cloud-native applications. I’m also impressed by the company’s focus on diversity, innovation, and continuous learning. I believe this environment will help me grow technically and professionally. Being a part of a product that is used by clients worldwide would be a great opportunity for me to make a meaningful contribution.
Q10. What do you understand by reusable UI components?
Answer:
Reusable UI components are small, independent parts of a user interface that can be used in multiple places across an application. For example, a button component, form input field, or navigation bar can be created once and reused in different pages. This approach helps in reducing code duplication, improving consistency, and making the application easier to maintain. In Angular, we can create components and use them with custom tags. Reusability also makes teamwork easier, as one developer can build components while others use them in different modules.
