Preparation Guide for the .NET Developer Position at Quality Feeds Limited
====================================================================
Purpose
-
This document outlines a step‑by‑step plan for candidates who want to meet
the requirements and excel in the interview process for the .NET Developer
role described above. Follow the actions in the order presented, allocating
time each week according to your current skill level and schedule.
1. Education and Core Knowledge Review (Week 1‑2)
a. Refresh the fundamentals of C (language versions 7‑10). Focus on
• data types, nullable reference types, pattern matching
• async/await, Tasks, value‑task, IAsyncEnumerable
• record types, init‑only setters, and other modern features
b. Re‑study Object‑Oriented Programming concepts and design patterns
(Factory, Repository, Unit of Work, CQRS, Mediator, Decorator, etc.).
Create a one‑page cheat sheet for quick reference.
c. Review SOLID principles and how they are applied in real‑world
.NET projects.
2. ASP.NET Core and .NET Framework Deep Dive (Week 3‑4)
a. Build a small end‑to‑end web API using ASP.NET Core 7.
• Include versioning, Swagger/OpenAPI, JWT authentication,
role‑based authorization.
• Implement a simple CRUD module backed by SQL Server.
b. Compare and contrast ASP.NET Core with the classic .NET Framework.
Identify scenarios where the older framework is still in use (legacy
maintenance) and practice migrating a tiny Web Forms or MVC app to
ASP.NET Core.
c. Study middleware pipeline, custom middleware, filters, and exception
handling strategies.
3. Database Mastery (Week 5‑6)
a. Design a normalized database for an agro‑processing scenario
(e.g., seed inventory, batch production, quality testing).
• Create tables, primary/foreign keys, indexes, and check constraints.
b. Write complex T‑SQL queries involving joins, CTEs, window functions,
and pivot/unpivot operations.
c. Develop stored procedures, table‑valued functions, and triggers
that demonstrate error handling and transaction control.
d. Use SQL Profiler/Extended Events to locate performance bottlenecks
and apply indexing or query refactoring techniques.
4. Microservices, CQRS, and Messaging (Week 7‑8)
a. Break the API from step 2 into two microservices (e.g., “Product”
and “Production”). Communicate via HTTP and via a message bus
(Azure Service Bus or RabbitMQ).
b. Implement CQRS:
• Separate command and query models.
• Use MediatR (or similar) for request handling.
• Persist read models in a separate denormalized table.
c. Practice publishing and consuming messages:
• Create a producer that publishes “BatchCreated” events.
• Create a consumer that updates inventory when the event is received.
5. Integration Skills (Week 9)
a. Consume a public REST API (e.g., a weather service) from a .NET client.
Handle authentication tokens, pagination, and error retries.
b. Build a SOAP client using WCF or the newer SoapCore package.
Connect to a mock legacy service that returns XML responses.
c. Demonstrate API versioning and contract testing (e.g., using Pact).
6. Front‑End Exposure (Optional but Advantageous) (Week 10)
a. Create a simple UI with ReactJS or Angular that calls the microservices
built earlier. Focus on:
• CRUD forms, data grids, and state management (Redux or NgRx)
• Handling authentication tokens and refresh flow
b. If time is limited, at least produce a static HTML/JS page that fetches
data from your API to show you understand the integration point.
7. DevOps and Agile Practices (Week 11)
a. Set up a Git repository (GitHub, GitLab or Azure DevOps). Commit
frequently, use feature branches, and write clear commit messages.
b. Create a basic CI pipeline that:
• Restores NuGet packages
• Builds the solution
• Runs unit tests (xUnit/NUnit)
• Publishes an artifact (Docker image or zipped binaries)
c. Familiarize yourself with Agile artifacts:
• Write user stories and acceptance criteria.
• Participate in a mock sprint planning and retrospective.
8. Testing and Documentation (Week 12)
a. Write unit tests for all business logic (minimum 80 % coverage).
Use mocking frameworks such as Moq.
b. Add integration tests that spin up an in‑memory SQL Server or use a
test container.
c. Produce technical documentation:
• API reference (Swagger + markdown)
• Architecture diagram (microservices, data flow, messaging)
• Database schema diagram
9. Portfolio and Resume Tailoring (Week 13)
a. Host your projects on GitHub/GitLab with a clean README:
• Project overview, tech stack, how to run locally, and key features.
• Screenshots of API docs and UI (if built).
b. Highlight experience that matches the job description:
• Agro‑industry related projects (even if simulated).
• Specific keywords: ASP.NET Core, Web API, CQRS, Microservices,
Service Bus, SQL Server, Async programming, OOP, Design Patterns.
c. Include quantifiable achievements in your resume:
“Reduced API response time by 35 % after indexing critical tables.”
“Delivered three microservices handling 2 M daily transactions.”
10. Interview Preparation (Week 14‑15)
a. Behavioral Questions:
• Prepare STAR‑based answers for teamwork, conflict resolution,
handling tight deadlines, and delivering during defect‑liability
periods.
b. Technical Questions:
• Explain the differences between ASP.NET Core and .NET Framework.
• Describe how you would design a CQRS system for seed inventory.
• Discuss strategies for handling message duplication in a Service Bus.
• Talk through async/await pitfalls and how to avoid deadlocks.
c. Live Coding:
• Practice coding on a whiteboard or shared screen: building a simple
endpoint, writing a LINQ query, or creating a stored procedure.
• Use platforms like LeetCode or HackerRank for algorithmic warm‑ups,
focusing on collections and concurrency.
d. System Design:
• Sketch an end‑to‑end architecture for a farm management platform.
Include databases, microservices, messaging, API gateway, caching,
and CI/CD pipeline.
11. Final Check‑list (Day Before the Interview)
• Verify that your GitHub profile is public and showcases the relevant repos.
• Print a PDF of your resume with the tailored bullet points.
• Review the company’s website (Quality Feeds Limited) to understand
their products, market, and recent news.
• Prepare questions to ask the interviewers:
– “What are the biggest technical challenges the team faces right now?”
– “How does the organization handle versioning and backward compatibility
for APIs used by agro‑processing partners?”
– “What CI/CD tools are currently in use, and is there a roadmap for
adopting containers or Kubernetes?”
By following this structured preparation plan you will:
* Meet or exceed every technical requirement listed in the job posting.
* Demonstrate domain awareness of agro‑based businesses.
* Show readiness to work in an agile, production‑oriented environment.
* Communicate confidence during behavioral and technical interviews.
Good luck, and may your code be clean and your deployments flawless!
