Testing a developer's skills before hiring reduces your risk of making a costly mistake. These practical evaluation methods help you assess technical ability, problem-solving, and communication style.
Quick Answer: Test a developer's skills by reviewing their portfolio, conducting a technical interview, assigning a small paid test project, checking their code quality on GitHub, and asking for references from past clients.
Start with portfolio review combined with specific questions. Ask the developer to explain their role in each project, challenges they faced, and how they solved them. A developer who can articulate their decisions clearly demonstrates both technical knowledge and communication skills. Look for projects relevant to businesses in Qatar and UAE.
Conduct a technical interview focused on problem-solving. Ask how they would approach common scenarios: improving a slow website, integrating a payment gateway, or handling a security vulnerability. Listen for structured thinking and practical solutions. Avoid trick questions. Real-world scenarios relevant to your project are more revealing.
Assign a small paid test project. This is the most reliable evaluation method. Give the developer a small task that requires skills similar to your main project. It could be building a simple landing page, creating a contact form with validation, or setting up a basic e-commerce product page. Pay them for this work. The test reveals their code quality, attention to detail, and reliability.
Review their code on GitHub or GitLab. Look at code organization, naming conventions, comments, and testing practices. Clean, well-structured code indicates a professional who cares about quality. Sloppy, disorganized code is a warning sign, regardless of how good their portfolio looks.
Check communication responsiveness. During the evaluation process, note how quickly they respond, how clearly they communicate, and whether they ask good questions. These communication patterns will persist throughout your project. Developers in Saudi Arabia and Dubai who communicate well during the hiring process typically maintain good communication during development.
Ask for and contact references. Speak directly with past clients about their experience. Ask about timeliness, communication, problem-solving, and whether they would hire the developer again. Louis Investments recommends talking to at least two past clients before making a final decision.
