Interview Questionnaire
14 Questions
- Q1. What are the benefits of the microservices?
- Ans.
Microservices offer benefits such as scalability, flexibility, and easier maintenance.
Scalability: Microservices can be scaled independently, allowing for better resource utilization.
Flexibility: Microservices can be developed and deployed independently, allowing for faster iteration and innovation.
Easier maintenance: Microservices are smaller and more focused, making it easier to identify and fix issues.
Improved fault...
- Q2. Differences between spring and spring boot?
- Ans.
Spring is a framework while Spring Boot is an extension of Spring.

Spring Boot reduces boilerplate code and simplifies application setup.
Spring Boot is opinionated and provides defaults for configuration.
Spring Boot is ideal for microservices and standalone applications.
Spring is more flexible and customizable than Spring Boot.

Examples of profile...
- Q5. How spring boot work internally?
- Ans.
Spring Boot is a framework that simplifies the development of Java applications by providing pre-configured settings and dependencies.
Spring Boot uses an embedded server to run applications.
It provides auto-configuration for commonly used libraries and frameworks.
Spring Boot uses Spring Framework's core features like Inversion of Control (IoC) and Aspect Oriented Programming (AOP).
It uses annotations to configure and c...
- Q6. If a microservice is down, then how can you handle that situation?
- Ans.
We can handle the situation by implementing fault tolerance mechanisms.
Implementing circuit breakers to prevent cascading failures
Using load balancers to redirect traffic to healthy instances
Implementing retry mechanisms to handle temporary failures
Using monitoring tools to detect and alert on failures
Implementing graceful degradation to provide partial functionality
Using backups or replicas to ensure high availability
- Q7. What kind of security added in your project and how?
- Q8. What are the transactions used in your projects?
- Q9. What are the spring boot annotations used in your project?
- Ans.
We use @RestController, @RequestMapping, @Autowired, @Service, @Repository, @Transactional, @GetMapping, @PostMapping, @PutMapping, @DeleteMapping annotations in our Spring Boot project.
@RestController - used to define RESTful web services
@RequestMapping - used to map HTTP requests to handler methods
@Autowired - used for automatic dependency injection
@Service - used to define a service layer component
@Repository - used...
- Q10. What is the use of spring data jpa?
- Ans.
Spring Data JPA simplifies the implementation of data access layer in Spring applications.
Provides a framework for easily creating repositories and queries
Reduces boilerplate code for data access layer
Supports pagination and sorting of data
Integrates with Spring's transaction management
Example: @Repository interface UserRepository extends JpaRepository
- Q11. What are the collection used in your project?
- Q12. Can you tell me how hash map internally work?
- Ans.
A hash map is a data structure that uses a hash function to map keys to values in constant time.
Hash map uses an array to store key-value pairs
The hash function is used to convert the key into an index of the array
Collisions occur when two keys map to the same index, which is resolved using chaining or open addressing
Retrieving a value from a hash map involves computing the hash of the key and then looking up the corre...
- Q13. Differences between comparable and comparator?
- Ans.
Comparable is an interface used for natural ordering while Comparator is an interface used for custom ordering.
Comparable is implemented by the class itself while Comparator is implemented by a separate class.
Comparable provides a single method compareTo() while Comparator provides a single method compare().
Comparable is used for sorting elements in a collection while Comparator is used for custom sorting.
Example: Stri...
- Q14. Tell me about concurrent Hash map?
- Ans.
Concurrent Hash Map is a thread-safe implementation of a hash map.
It allows multiple threads to access and modify the map concurrently.
It uses a technique called lock striping to achieve high concurrency.
It is part of the java.util.concurrent package in Java.
Example: ConcurrentHashMap in Java.

- Q1. What is node js?
- Ans.
Node.js is a runtime environment that allows you to run JavaScript code outside of a web browser.
Node.js is built on Chrome's V8 JavaScript engine.
It uses an event-driven, non-blocking I/O model.
Node.js is commonly used for building server-side applications.
It has a large ecosystem of open-source libraries and frameworks like Express.js.
- Q2. What is event loop?
- Ans.
Event loop is a mechanism that allows a program to efficiently handle multiple events or tasks concurrently.
Event loop is commonly used in asynchronous programming to manage tasks that may take varying amounts of time to complete.
It continuously checks for events or tasks in a queue and executes them one by one.
Event loop helps prevent blocking of the main thread by allowing non-blocking execution of tasks.

- Q3. Difference between callback and promise?
- Ans.
Callback is a function passed as an argument to another function to be executed later, while a promise is an object representing the eventual completion or failure of an asynchronous operation.
Callback is used in traditional asynchronous programming, while promises are used in modern asynchronous programming.
Callbacks can lead to callback hell or pyramid of doom, while promises provide better readability and error hand...
- Q4. What is middlewares in node js?
- Ans.
Middlewares in Node.js are functions that have access to the request and response objects, and can modify or terminate the request-response cycle.
Middlewares are functions that are executed in the middle of the request-response cycle.
They can perform tasks like parsing request data, logging, authentication, etc.
Middlewares can be added using app.use() method in Express framework.
Example: app.use(bodyParser.json()) to p
- Q5. What is event emitter?
- Ans.
Event emitter is a pattern used to handle and respond to events in software development.
Event emitter is a design pattern commonly used in Node.js for handling events.
It allows objects to subscribe to events and be notified when those events occur.
Event emitter is often used for asynchronous programming and decoupling components.
Example: EventEmitter class in Node.js can be used to create custom events and handle them.
