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

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

Data bricks processing on reporting layer impacts data latency.

• Data bricks processing can improve reporting performance by processing data in parallel.

• However, it can also introduce latency if not optimized properly.

• Optimizing data bricks processing involves tuning cluster configurations and optimizing queries.

• Using caching mechanisms can also help reduce data latency in reporting.

• Monitoring and analyzing data latency regularly is crucial for identifying bottlenecks and optim...read more

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

Rotational shift can be acceptable depending on individual preferences and work-life balance.

• Rotational shifts can provide flexibility for employees with different schedules or preferences.

• Some individuals may thrive in a rotational shift environment, while others may find it challenging to adjust.

• It is important for employers to consider the impact of rotational shifts on employee well-being and productivity.

• Communication and planning are key to successfully implementing rot...read more

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
