Majesco Interview Questions, Process, and Tips

Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.

• Dependency injection helps in achieving loose coupling between classes.

• It allows for easier testing by providing a way to mock dependencies.

• There are three types of dependency injection: constructor injection, setter injection, and interface injection.

Our current project architecture follows a microservices design pattern with Docker containers for scalability and flexibility.

• Microservices architecture

• Docker containers for scalability

• RESTful APIs for communication

• Kubernetes for orchestration

Software testing is the process of evaluating a software application to ensure it meets specified requirements and functions correctly.

• Identifying defects or bugs in the software

• Verifying that the software meets the specified requirements

• Ensuring the software functions correctly under different conditions

• Types of software testing include unit testing, integration testing, system testing, and acceptance testing

Underwriting is the process of evaluating the risk of insuring a person or asset and determining the premium to be charged.

• Underwriting involves assessing the risk associated with insuring a particular individual or asset.

• Factors such as age, health, occupation, and lifestyle are considered during underwriting.

• The underwriter determines the premium to be charged based on the assessed risk.

• Underwriting is commonly used ...read more

Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.

• Hashmap uses a hash function to map keys to indices in an array.

• It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.

• In case of collisions, separate chaining or open addressing techniques are used to handle them.

• Example: HashMap map = new HashMap<>(); ma

Inheritance in Java allows a class to inherit properties and behavior from another class.

• Allows a class to inherit fields and methods from another class

• Promotes code reusability and reduces redundancy

• Uses the 'extends' keyword to establish a parent-child relationship

• Child class can access non-private members of the parent class

Interface in Java is a blueprint of a class that defines a set of methods without implementation.

• Interfaces can have abstract methods and constants

• Classes can implement multiple interfaces

• Interfaces are used for achieving abstraction and multiple inheritance

Collection framework in Java provides a set of interfaces and classes to store and manipulate groups of objects.

• Includes interfaces like List, Set, Map

• Classes like ArrayList, LinkedList, HashSet, HashMap

• Provides methods for adding, removing, and accessing elements

• Allows for easy iteration and manipulation of collections
