VB.Net Interview Questions and Answers

Description

• VB.Net Interview Questions and Answers basic to Advanced, Real-time Scenario-Based and Coding Based

  A progressive VB.Net topic map for that moves from language fundamentals and application development to architecture, performance, and strategic leadership.

   

  Focus on language fundamentals, object‑oriented programming, WinForms/WPF basics, ADO.NET, LINQ, exception handling, debugging, unit testing, and building CRUD applications; be comfortable with Visual Studio tooling and NuGet package management.

   

  Advance into application architecture and integration: asynchronous programming (async/await), advanced LINQ, Entity Framework optimization, web apps with ASP.NET, Web API design, RESTful services, authentication/authorization, and automated testing strategies.

   

  Emphasize scalability and reliability: performance profiling and tuning, memory management, multithreading and concurrency patterns, distributed caching, microservices integration, CI/CD pipelines for .NET, and migration strategies to newer .NET runtimes.

   

  Drive architecture and strategy: system and platform design, cross‑team API contracts, cloud native .NET at scale, governance and security policies, cost and risk tradeoffs, technical leadership, mentoring, and roadmap planning for modernization.

  Next steps for hiring and development

  Use hands‑on coding tasks for juniors, design and optimization case studies for mid levels, and architecture plus leadership presentations for senior/principal hires; pair these with project portfolios and targeted interview rubrics.
