JOBWAVE INSIGHTS

Who is this for?

This is a junior .NET full-stack/web developer role for someone with at least 1 year of experience who can work across C#/.NET Core, REST APIs, Angular, React, and SQL Server.

The strongest candidate will be comfortable handling both backend and frontend development rather than focusing only on .NET.

Key Skills

• C#
• .NET Core 9+
• REST APIs / Web APIs
• Angular 16+
• React JS
• JavaScript
• TypeScript
• HTML / CSS
• MS SQL Server
• SQL queries
• Stored procedures
• Git / GitLab / GitHub
• Unit testing
• Debugging
• Production troubleshooting

Priority Skills

Highest Priority

1. C# and .NET Core 9+
2. Angular 16+
3. MS SQL Server
4. REST API development
5. JavaScript / TypeScript
6. React JS
7. Debugging and troubleshooting

Strong Advantages

• Strong SQL query optimization
• Stored procedures and functions
• Git/GitHub/GitLab workflows
• Unit testing
• Third-party API integrations
• Production support experience
• Good understanding of software development best practices

What to Prepare

• C# fundamentals
• .NET Core architecture
• REST API development
• Dependency Injection
• Entity Framework/Core concepts
• Angular 16+
• React fundamentals
• TypeScript
• SQL Server
• Query optimization
• Stored procedures
• API integration
• Git
• Unit testing
• Debugging and production support

What to Focus On

1. C# & .NET Core

This is the primary backend requirement. Prepare C# fundamentals, OOP, collections, LINQ, async/await, exception handling, dependency injection, middleware, configuration, and Web API development.

2. Angular

Angular is specifically listed as a hands-on requirement and is likely to receive more attention than React. Prepare components, services, routing, forms, RxJS, HTTP calls, lifecycle hooks, and TypeScript.

3. SQL Server

Be ready to write SQL queries and explain how you would optimize slow queries. Stored procedures, functions, joins, indexes, transactions, and execution plans are useful preparation areas.

4. REST APIs

Prepare how to design, consume, secure, validate, test, and troubleshoot REST APIs. Understand HTTP methods, status codes, authentication, error handling, and API integration.

5. Full-Stack Integration

The role expects you to connect the frontend with the .NET backend and database. Be prepared to explain a complete flow:

Angular/React → REST API → .NET Core → SQL Server

6. Troubleshooting

The role includes production support. Prepare examples of debugging application errors, API failures, database problems, and frontend issues.

• Angular 16+: The role specifically asks for hands-on Angular, so prepare practical development questions.
• React: React is also required, although Angular appears to be the stronger frontend requirement.
• SQL Server: Weak SQL knowledge could be a significant gap because database work is explicitly included.
• REST APIs: Be able to demonstrate APIs you have actually developed or integrated.
• TypeScript: Prepare beyond basic JavaScript syntax because Angular development relies heavily on TypeScript.
• Production support: Have at least one example of debugging and resolving a real application issue.
• Git: Understand branching, commits, merge/pull requests, conflict resolution, and basic Git workflows.
