10+ Majik Medical Solutions Interview Questions and Answers

The interviewer asked about Pega certification, Java in Pega, OOPs, Inheritance, Activities, and Ruleset.

• Pega is a BPM tool that uses Java for coding.

• OOPs stands for Object-Oriented Programming and is a programming paradigm.

• There are four types of inheritance: Single, Multiple, Multilevel, and Hierarchical.

• Activities are used in Pega to perform a specific task or set of tasks.

• Ruleset is a collection of rules that define the behavior of an application.

Angstrom number is a number whose sum of cubes of digits is equal to the number itself.

• Take input number

• Separate digits

• Cube each digit

• Sum the cubes

• Compare with input number

To print numbers 1 to 100 and check if they are prime or not.

• Use a loop to iterate through numbers 1 to 100

• For each number, check if it is prime or not

• Print the number and whether it is prime or not

The 4 pillars of OOPs are Abstraction, Encapsulation, Inheritance, and Polymorphism.

• Abstraction: Hiding complex implementation details and showing only essential features.

• Encapsulation: Binding data and functions together to protect data from outside interference.

• Inheritance: Creating new classes from existing ones, inheriting properties and methods.

• Polymorphism: Ability of objects to take on multiple forms, allowing flexibility and extensibility.

I have worked on projects involving the development of novel features such as machine learning algorithms for predictive analytics.

• Developed machine learning algorithms to predict customer churn in a telecom company.

• Implemented natural language processing techniques for sentiment analysis in social media data.

• Created a recommendation system based on collaborative filtering for an e-commerce platform.

DL uses neural networks with multiple layers to learn complex patterns, while ML uses algorithms to learn from data.

• DL uses deep neural networks with multiple layers, while ML uses simpler algorithms like decision trees or SVMs.

• DL requires large amounts of data to train effectively, while ML can work with smaller datasets.

• DL is more computationally intensive and requires more processing power compared to ML.

• DL is better suited for tasks like image and speech recognition, whil...read more

My college final year project was a web-based application for online shopping with features like user authentication, product search, and order tracking.

• Developed using Java for backend and HTML/CSS/JavaScript for frontend

• Implemented OOPS concepts like inheritance, encapsulation, and polymorphism

• Used MySQL database for storing user information and product details

• Integrated payment gateway for secure transactions

• Collaborated with team members to design and develop the project

The 5 pillars of OOPs concept are Inheritance, Encapsulation, Polymorphism, Abstraction, and Class/Object.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex implementation details and showing only the necessary features.

• Class/Object: Blueprint for creatin...read more

Encapsulation and inheritance are key concepts in object-oriented programming.

• Encapsulation: hiding the internal state of an object and restricting access to it. Example: using private variables and public methods in a class.

• Inheritance: allowing a class to inherit properties and behavior from another class. Example: a 'Dog' class inheriting from an 'Animal' class.

Tree data structure is a hierarchical data structure with nodes connected by edges.

• Variations include binary trees, binary search trees, AVL trees, red-black trees, etc.

• Trees can be used to represent hierarchical relationships like file systems, organization structures, etc.

• Traversal methods include in-order, pre-order, post-order, and level-order traversal.

Java is a high-level, object-oriented programming language used for developing desktop, web, and mobile applications.

• Java is platform-independent and can run on any operating system with the help of JVM.

• It follows the OOPS concepts like inheritance, encapsulation, polymorphism, and abstraction.

• Java has a vast library of pre-built classes and APIs that make development faster and easier.

• Java is used for developing various applications like Android apps, web applications, enter...read more

Object-oriented programming paradigm that focuses on objects and classes for code organization and reusability.

• Encapsulation: Bundling data and methods that operate on the data into a single unit (object)

• Inheritance: Ability of a class to inherit properties and behavior from another class

• Polymorphism: Ability to present the same interface for different data types

• Abstraction: Hiding the complex implementation details and showing only the necessary features

The 4 pillars of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Abstraction: Hiding the complex implementation details and showing only the necessary features of an object.

• Polymorphism: Ability of an object to take on many forms.
