10+ InGen Dynamics Interview Questions and Answers

Multithreading involves executing multiple threads concurrently within the same process, while asynchronous programming allows tasks to be executed independently of the main program flow.

• Multithreading involves multiple threads running concurrently within the same process, sharing resources and potentially causing synchronization issues.

• Asynchronous programming allows tasks to be executed independently of the main program flow, enabling non-blocking operations and improved pe...read more

Unit testing focuses on testing individual components in isolation, while integration testing focuses on testing how multiple components work together.

• Unit testing is done on individual units or components of a software application, such as functions or classes.

• Integration testing is done to test how different units or components work together as a whole system.

• Unit testing is usually done by developers during the development phase, while integration testing is typically done...read more

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 focuses on creating objects that interact with each other to solve problems.

• Encapsulation is a key concept in OOP, where data is kept private within a class and accessed through public methods.

• Inheritance allows classes to inherit attributes and methods from other classes.

• Polymorphism enables objects to be t...read more

To write an API, define endpoints, request/response formats, authentication, and documentation.

• Define endpoints for different functionalities (e.g. GET /users, POST /users)

• Specify request and response formats (e.g. JSON)

• Implement authentication mechanisms (e.g. OAuth)

• Document the API using tools like Swagger or Postman

Multithreading in Java allows multiple threads to execute concurrently, improving performance and responsiveness.

• Multithreading allows multiple tasks to run concurrently within a single program

• Threads share the same memory space, allowing for efficient communication and data sharing

• Java provides built-in support for multithreading through the Thread class and Runnable interface

• Example: Creating a new thread by extending the Thread class or implementing the Runnable interface

Spring Boot is a framework that simplifies the development of Java applications by providing pre-configured setups.

• Spring Boot eliminates the need for manual configuration by providing default settings.

• It allows developers to create stand-alone, production-grade Spring-based Applications.

• Example: Creating a RESTful web service using Spring Boot.

Adhoc testing is an informal testing technique without any predefined test cases. Sanity testing is a quick test to check if the critical functionalities are working as expected.

• Adhoc testing is performed without any formal test plan or test cases

• It is usually performed by the testers to identify defects that may have been missed in formal testing

• Sanity testing is a subset of regression testing

• It is performed to check if the critical functionalities of the application are wor...read more

• CTC (Cost to Company) includes salary, bonuses, benefits, and other perks offered by the company.

• Expectations may include experience level, skills, responsibilities, and goals for the role.

• CTC and expectations can vary based on company size, industry, location, and candidate's qualifications.

• For example, a Test Manager may expect a CTC of $80,000 with responsibilities to lead testing efforts, manage a team, ...read more

A test plan is a document that outlines the scope, approach, resources, and schedule of testing activities.

• Defines the objectives and scope of testing

• Outlines the testing approach and methodologies to be used

• Specifies the resources, schedule, and responsibilities for testing

• Includes test scenarios, test cases, and test data

• Identifies risks and mitigation strategies

• Provides a basis for monitoring and controlling the testing process

Test strategy is a high-level plan to achieve testing objectives and goals.

• Test strategy outlines the approach to be taken for testing a particular project or product.

• It includes the scope of testing, resources, timelines, and risks involved.

• Test strategy helps in ensuring that testing is conducted in a systematic and organized manner.

• Examples: Agile testing strategy, risk-based testing strategy, automation testing strategy.

RTM stands for Requirements Traceability Matrix. It is a document that links requirements to test cases to ensure all requirements are tested.

• RTM is a tool used in software testing to ensure all requirements are tested.

• It links requirements to test cases and helps in tracking the progress of testing.

• It helps in identifying any gaps in testing and ensures complete test coverage.

• RTM is useful in maintaining the quality of the software product.

• Example: If a requirement states th...read more

• Personal

• Intimate

Using a type field in a table allows for polymorphic associations between different models.

• The type field stores the name of the associated model.

• This allows for easy querying and retrieval of associated records.

• Example: a comments table can have polymorphic associations with both posts and articles.

• The type field would store either 'Post' or 'Article' depending on the associated record.

STLC stands for Software Testing Life Cycle which is a process followed to ensure software quality.

• STLC involves planning, designing, executing and reporting of tests.

• It includes various phases such as requirement analysis, test planning, test design, test execution, and test closure.

• Each phase has its own set of activities and deliverables.

• STLC helps in identifying defects early in the development cycle, reducing the cost of fixing defects.

• It ensures that the software meets ...read more
