Perceptive Senior Software Engineer Interview Questions, Process, and Tips

Azure PAAS, IAAS, and SAAS are different cloud service models provided by Microsoft Azure.

• PAAS (Platform as a Service) - Provides a platform for developers to build, deploy, and manage applications without worrying about infrastructure.

• IAAS (Infrastructure as a Service) - Provides virtualized computing resources over the internet, such as virtual machines, storage, and networking.

• SAAS (Software as a Service) - Delivers...read more

Dependency Injection is a design pattern in which a class receives its dependencies from external sources rather than creating them itself.

• Dependency Injection helps in achieving loose coupling between classes.

• It allows for easier testing and maintenance of code.

• There are three common ways to achieve Dependency Injection: Constructor Injection, Setter Injection, and Interface Injection.

Interfaces define a contract for classes to implement, while abstract classes provide partial implementation.

• Use interfaces when you want to define a contract that multiple classes can implement.

• Use abstract classes when you want to provide some common functionality to multiple classes.

• Interfaces support multiple inheritance, while classes can only inherit from one abstract class.

• Interfaces are used for loose coupling ...read more

Solid principles are a set of five design principles for writing clean, maintainable, and scalable code.

• Single Responsibility Principle (SRP) - A class should have only one reason to change.

• Open/Closed Principle (OCP) - Software entities should be open for extension but closed for modification.

• Liskov Substitution Principle (LSP) - Objects of a superclass should be replaceable with objects of its subclasses without affe...read more

I use Logic Apps for automating workflows and Service Bus for reliable messaging.

• I use Logic Apps to create automated workflows for integrating various systems and services.

• I leverage Service Bus for reliable messaging between different components of a distributed system.

• For example, I have used Logic Apps to automate data transfers between CRM systems and databases, and Service Bus for decoupling microservices in a cl
