10+ Technology Architect Interview Questions and Answers

DevOps pipelines automate the software delivery process, integrating code changes from development to production.

• DevOps pipelines are automated workflows that allow for continuous integration and continuous delivery (CI/CD) of software.

• Azure DevOps provides tools for creating, managing, and executing DevOps pipelines.

• Pipelines in Azure DevOps can be defined using YAML or through a visual designer.

• They typically consist of stages, jobs, and tasks that automate the build, test,...read more

Answering questions related to current project architecture, designing scalable micro services, ensuring CI/CD, OAuth, and authorization servers.

• Current project architecture involves a detailed analysis of the existing system, identifying key components, and designing a scalable solution.

• Designing micro services to be scalable requires breaking down the application into smaller, independent services that can be easily deployed and managed.

• Ensuring CI/CD works as expected invo...read more

Design patterns are reusable solutions to common problems in software design. Singleton pattern ensures a class has only one instance and provides a global point of access to it.

• Design patterns are best practices for solving common design problems in software development.

• Singleton pattern restricts the instantiation of a class to one object, ensuring there is only one instance of the class.

• Singleton pattern provides a global point of access to the instance, allowing it to be ...read more

OOP 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.

• Encapsulation: Objects can encapsulate data and behavior within a single unit.

• Inheritance: Objects can inherit attributes and methods from other objects.

• Polymorphism: Objects can take on different forms or have multiple behaviors.

• Abstraction: Objects can represent real-world entities with simplified models.

• Example: In a car object, the...read more

Commonly used design patterns in .NET include Singleton, Factory, Observer, and MVC.

• Singleton pattern ensures a class has only one instance and provides a global point of access to it.

• Factory pattern creates objects without specifying the exact class of object that will be created.

• Observer pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.

• MVC (Model-View-Controller) pattern...read more

Advantages of using .NET Core include cross-platform compatibility, high performance, and open-source nature.

• Cross-platform compatibility allows for development on Windows, macOS, and Linux.

• High performance due to its modular architecture and optimized runtime.

• Open-source nature encourages community contributions and rapid updates.

• Support for modern development practices like microservices and containerization.

• Integration with popular development tools like Visual Studio and ...read more

We follow a thorough code review process to ensure quality and consistency.

• All code changes are reviewed by at least one other team member.

• We use code review tools like GitHub pull requests or Crucible.

• Reviewers check for adherence to coding standards, functionality, and potential bugs.

• Feedback is given constructively and improvements are made before merging into the main branch.

I manage a team of developers by setting clear goals, providing support and resources, fostering collaboration, and promoting a positive work culture.

• Set clear goals and expectations for the team

• Provide necessary support, resources, and training for team members

• Foster collaboration and communication among team members

• Promote a positive work culture and provide feedback and recognition for achievements

HLD stands for High-Level Design and LLD stands for Low-Level Design. They are created to plan and document software architecture.

• HLD is a conceptual design that outlines the overall structure of the software system.

• LLD is a detailed design that specifies the implementation details of the software system.

• HLD is created first, followed by LLD.

• HLD includes system architecture, modules, interfaces, and data flow.

• LLD includes algorithms, data structures, database schema, and code...read more

Landscape and Architect solution involves analyzing the current technology landscape and designing a solution that aligns with business goals.

• Understand current technology infrastructure and systems

• Identify business goals and requirements

• Design a solution that integrates with existing systems and meets business needs

• Consider scalability, security, and performance

• Create a roadmap for implementation and migration

Binary search is a search algorithm that finds the position of a target value within a sorted array.

• It works by repeatedly dividing the search space in half.

• Compare the target value with the middle element of the array.

• If the target value is smaller, search the left half of the array.

• If the target value is larger, search the right half of the array.

• Repeat until the target value is found or the search space is empty.

High Level Design (HLD) of a lift includes system architecture, components, interfaces, and interactions.

• Identify key components like motor, control panel, doors, and sensors

• Define system architecture including how components interact

• Specify interfaces for user input, floor selection, and emergency stop

• Consider safety features like overload protection and emergency brakes
