• Designing the deployment strategy for a .NET Core microservices application on Azure, considering scalability , resilience , and cost-effectiveness .(Expertise Level: Mid to Expert)

  • Scenario: Design an authentication and authorization flow for a multi-tenant ASP.NET Core application where users belong to specific organizations and have roles within those organizations .

  • Scenario: You need to build an API that aggregates data from multiple downstream microservices, handling potential latency and failures gracefully. How would you design this API using ASP.NET Core ?

  • Scenario: You need to design a system where multiple .NET Core services need to react to events happening in other services reliably using asynchronous messaging . How would you architect this?

  • How would you investigate and resolve an API endpoint in your ASP.NET Core application experiencing high latency under load?

  • How would you mentor junior developers working with .NET Core / ASP.NET Core ?

  • How do you stayupdatedwith the latestfeatures and changesin the.NETandASP.NET Coreecosystem?

  • How do you ensure consistency , maintainability , and adherence to best practices across multiple ASP.NET Core projects or teams?

  • Describe your process for conducting code reviews for .NET Core / ASP.NET Core projects. What specific things do you look for?

  • As a Tech Lead, how would you establish and enforcecoding standardsandbest practiceswithin your team for.NET Core/ASP.NET Coredevelopment?

  • Describe acomplex architectural decisionyou made on a.NET Core/ASP.NET Coreproject, including thetrade-offsyou considered.

  • How do you ensure yoursoftware architecture aligns with business goalsand canadapt to changing requirements?

  • As a Tech Lead/Architect, how do you decide on the appropriate architecture (e.g.,Monolith,Microservices,Modular Monolith) for a newASP.NET Coreproject based onrequirements?

  • Imagine you need to migrate a legacyASP.NET application(Web Forms or MVC) toASP.NET Core. What would be your strategy , key considerations , and potential challenges ?

  • Explain the role of containerization (e.g., Docker ) in deploying .NET Core/ASP.NET Core applications. How does Kubernetes fit into this?

  • How do you approach logging and monitoring in a distributed .NET Core/ASP.NET Core application or microservices environment ?

  • How do you manage secrets and sensitive configuration data securely in a .NET Core application, especially when deploying to the cloud (e.g., Azure Key Vault)? Mid Level

  • Describe how you would integrate a .NET Core application with specific Azure services like Azure Functions, Azure SQL Database, Azure Service Bus, or Azure Blob Storage.Expertise Level: Mid-Level to Expert

  • How would you design ascalableandresilient.NET Core/ASP.NET Coreapplication deployed to acloud environmentlikeAzure? Discuss relevant Azure services (App Service,AKS,Load Balancer,Application Gateway).

  • Explain how you would implement health checks in an ASP.NET Core application, particularly in a microservices or containerized environment.

  • How do you handle API versioning in ASP.NET Core Web API ?

  • Explain the concept of idempotency and why it's important , especially in distributed systems or APIs .

  • How do you handle distributed transactions or ensure data consistency across multiple microservices (e.g., Saga pattern , eventual consistency )?

  • Explain the Circuit Breaker pattern and its importance in a microservices architecture .

  • What is anAPI Gateway pattern, and what role does it play inmicroservices?
