Round 1 - Technical 

(6 Questions)

  • Q1. What is the role of exception handling in programming, and how is the 'finally' block used in this context, as well as the process of throwing exceptions?
  • Ans. 

    Exception handling is crucial in programming to handle errors and ensure proper execution. The 'finally' block is used to clean up resources, and throwing exceptions allows for error propagation.

    • Exception handling is used to manage errors and unexpected situations in a program.

    • The 'finally' block is used to execute code that should always run, regardless of whether an exception is thrown or not.

    • Throwing exceptions allo...

  • Q2. What are the differences between SQL and NoSQL databases, and can you mention some NoSQL databases that you are familiar with?
  • Q3. What are the ACID properties implemented in your project, and can you provide a brief overview of the CAP Theorem?
  • Ans. 

    ACID properties ensure data integrity in transactions. CAP Theorem states that a distributed system can only guarantee two out of three: Consistency, Availability, Partition Tolerance.

    • ACID properties: Atomicity, Consistency, Isolation, Durability

    • Example: In a banking application, a transfer of funds should be atomic, consistent, isolated, and durable

    • CAP Theorem: Consistency, Availability, Partition Tolerance - a distri...

  • Q4. Database disaster recovery?
  • Q5. What is the difference between Comparable and Comparator in Java? And how to Implement in Collections.
  • Ans. 

    Comparable is an interface used for natural ordering, while Comparator is used for custom ordering in Java Collections.

    • Comparable interface is used to define the natural ordering of objects. It is implemented by the class whose objects are to be sorted.

    • Comparator interface is used to define custom ordering of objects. It is implemented by a separate class.

    • To implement Comparable, the class needs to override the compare...

  • Q6. Implementation of Generics in Java
  • Ans. 

    Generics in Java allow for creating classes, interfaces, and methods that operate on types parameterized at compile time.

    • Generics provide type safety by allowing compile-time type checking.

    • They enable code reusability and reduce the need for casting.

    • Example: List<String> list = new ArrayList<>();

Round 2 - Technical 

(10 Questions)

  • Q1. Can you provide the code to reverse a string using recursion?
  • Ans. 

    Code to reverse a string using recursion

    • Create a recursive function that takes a string as input

    • Base case: if the string is empty or has only one character, return the string

    • Recursive case: return the last character of the string concatenated with the result of calling the function on the substring excluding the last character

  • Answered by AI
  • Q2. How does object comparison work with specific fields?
  • Ans. 

    Object comparison with specific fields involves comparing values of selected fields between two objects.

    • Object comparison can be done by comparing the values of specific fields in two objects.

    • Fields can be selected based on unique identifiers or criteria for comparison.

    • Example: Comparing the 'name' field of two person objects to check if they are the same.

  • Answered by AI
  • Q3. How does the distributed transactions being handled in a microservice?
  • Ans. 

    Distributed transactions in microservices involve using compensating transactions and event-driven architecture.

    • Microservices typically use compensating transactions to maintain consistency across multiple services.

    • Event-driven architecture can help in coordinating distributed transactions by using events to trigger actions in different services.

    • Implementing distributed transactions in microservices requires careful de...

  • Answered by AI
  • Q4. Aggregator Pattern in Microservice
  • Ans. 

    Aggregator pattern is used in microservices architecture to combine multiple service responses into a single response.

    • Aggregator pattern helps in reducing the number of client requests by combining multiple service responses.

    • It can be implemented using a separate service or within an existing service.

    • Example: A shopping website aggregating product information from different microservices like inventory, pricing, and re

  • Answered by AI
  • Q5. What is the implementation of the factory design pattern?
  • Ans. 

    Factory design pattern is a creational pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.

    • Factory method pattern defines an interface for creating objects, but lets subclasses decide which class to instantiate.

    • It promotes loose coupling by eliminating the need to bind application-specific classes into the code.

    • Example: A car m...

  • Q6. What is indexing in a database, and what data structures are commonly used for indexing?
  • Ans. 

    Indexing in a database is a technique to improve the speed of data retrieval by creating a data structure that allows for quick lookup.

    • Indexing involves creating a separate data structure that contains pointers to the actual data in the database.

    • Common data structures used for indexing include B-trees, hash tables, and binary search trees.

    • Indexes can be created on one or multiple columns in a database table to speed up...

  • Answered by AI
  • Q7. What is your approach to designing a system capable of handling thousands of requests?
  • Ans. 

    My approach involves using load balancing, caching, asynchronous processing, and horizontal scaling.

    • Implement load balancing to distribute requests evenly across multiple servers.

    • Utilize caching mechanisms to store frequently accessed data and reduce response times.

    • Use asynchronous processing for long-running tasks to free up resources for handling more requests.

    • Implement horizontal scaling by adding more servers to ha...

  • Answered by AI
  • Q8. What is the CQRS pattern in microservices?
  • Ans. 

    CQRS pattern in microservices separates read and write operations for improved scalability and performance.

    • CQRS stands for Command Query Responsibility Segregation

    • It separates the read and write operations into two different models

    • Write operations update the data store, while read operations query a separate data store

    • CQRS can improve performance and scalability by allowing each model to be optimized for its specific t

  • Answered by AI
  • Q9. What is the role of API Gateway in microservices architecture?
  • Ans. 

    API Gateway acts as a single entry point for all client requests in a microservices architecture.

    • API Gateway handles authentication, authorization, rate limiting, and routing of requests to appropriate microservices.

    • It helps in decoupling client applications from individual microservices, providing a more flexible and scalable architecture.

    • API Gateway can also perform tasks like request/response transformation, logging...

  • Q10. Write SQL query to fetch data from two tables using joins?
  • Ans. 

    SQL query to fetch data from two tables using joins

    • Use the JOIN keyword to combine rows from two tables based on a related column

    • Specify the columns to select from each table in the SELECT statement

    • Use the ON keyword to specify the join condition
