10+ Emonics Technologies Interview Questions and Answers

Object-oriented programming is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.

• OOP is a programming paradigm that uses objects to structure code

• Objects have attributes (fields) and behaviors (methods)

• Encapsulation, inheritance, and polymorphism are key principles of OOP

• Example: A 'Car' object may have attributes like 'color' and 'model' and behaviors like 'drive' and 'stop'

My favorite subject apart from programming courses is mathematics.

• I enjoy solving complex problems and puzzles in mathematics.

• I find the logical and analytical thinking required in mathematics fascinating.

• Mathematics helps me improve my problem-solving skills, which are crucial in software development.

• I appreciate the beauty and elegance of mathematical concepts and theories.

• Some of my favorite topics in mathematics include calculus, algebra, and number theory.

Automate a website using code

• Use Selenium WebDriver to automate interactions with the website

• Identify elements on the website using CSS selectors or XPaths

• Perform actions like clicking buttons, filling forms, and verifying text

• Handle waits for elements to load properly

• Use programming languages like Java, Python, or JavaScript for scripting

Reverses strings in an array and adds stars between characters

• Iterate through each string in the array

• Reverse each string using built-in functions or manual reversal

• Add stars between characters in the reversed string

• Return the modified array of strings

An abstract class is a class that cannot be instantiated and is used as a base for other classes.

• An abstract class can have abstract methods that must be implemented by its subclasses.

• It can also have non-abstract methods that can be inherited by its subclasses.

• An abstract class provides a common interface for its subclasses.

• It is used to achieve abstraction and provide a blueprint for other classes.

TCP (Transmission Control Protocol) and IP (Internet Protocol) are the foundational protocols of the internet.

• TCP is responsible for establishing and maintaining a reliable connection between two devices.

• IP is responsible for routing and addressing packets of data across networks.

• TCP/IP together form the basis of internet communication.

• Example: When you visit a website, TCP ensures the data packets are delivered in the correct order, while IP ensures they reach the correct de...read more

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.

• Polymorphism is a fundamental concept in object-oriented programming.

• It allows for code reusability and flexibility.

• Polymorphism can be achieved through method overriding and method overloading.

• Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can all be treated as Animals.

• Example: A method can accept ...read more

An automation framework is a set of guidelines, rules, and tools that help in creating and executing automated tests.

• Provides structure and organization for automated testing

• Defines how tests are written, executed, and reported

• Includes libraries, utilities, and templates for test automation

• Supports integration with test management tools and version control systems

• Examples: Selenium WebDriver, TestNG, JUnit, Cucumber

PL/SQL queries using where clause allow filtering of data based on specified conditions.

• Use WHERE clause to specify conditions for filtering data

• Conditions can include comparisons, logical operators, and functions

• Example: SELECT * FROM table_name WHERE column_name = 'value'

A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward.

• Create a string variable with a word or phrase that is the same forward and backward.

• Use a loop to compare the characters from the beginning and end of the string to check if it is a palindrome.

• Ignore spaces and punctuation when checking for palindromes.

• Example: 'racecar' is a palindrome.

Agile ceremonies are regular meetings or events in Agile methodology to facilitate communication, collaboration, and decision-making within the team.

• Sprint Planning: Setting goals and planning work for the upcoming sprint.

• Sprint Review: Demo of completed work to stakeholders for feedback.

• Sprint Retrospective: Reflecting on the sprint and identifying areas for improvement.

• Backlog Groomin...read more

Joins in SQL are used to combine rows from two or more tables based on a related column between them.

• Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN

• INNER JOIN returns rows when there is at least one match in both tables

• LEFT JOIN returns all rows from the left table and the matched rows from the right table

• RIGHT JOIN returns all rows from the right table and the matched rows from the left table

• FULL JOIN returns rows when there is a match in one of the t...read more

Find the third largest string in an array of strings.

• Sort the array in descending order.

• Skip the first two elements and return the third element.

Procedures do not return values while functions return values.

• Procedures are used to perform an action while functions are used to calculate a value.

• Functions can be used in expressions while procedures cannot.

• Functions have a return type while procedures do not.

• Procedures can modify the input parameters while functions cannot.

• Examples of functions include SUM, AVG, and MAX while examples of procedures include INSERT, UPDATE, and DELETE.

Order management is the process of receiving, tracking, and fulfilling customer orders.

• It involves managing the entire order lifecycle from order placement to delivery

• It includes tasks such as inventory management, order processing, and shipping

• Order management systems help automate and streamline the process
