- Strong understanding of core concepts: Ensure they have a solid grasp of concurrency, goroutines, channels, and data structures.
- Familiarity with relevant frameworks and libraries: Depending on your project, experience with frameworks like Gin, Echo, or Beego might be essential.
- Good communication skills: Clear and proactive communication is crucial for remote collaboration.
- Version control proficiency: Experience with Git is essential for collaborative development.
Main expertise areas within Golang
Golang freelancers can specialise in various areas, including:
- Web development (backend): Building RESTful APIs, microservices, and web applications.
- Devops and cloud infrastructure: Creating and managing cloud-based systems using tools like Docker and Kubernetes.
- Data processing and analysis: Developing data pipelines and analytical tools.
- Concurrent programming: Building highly concurrent and parallel systems.
- Command-line interface (CLI) development: Creating efficient and user-friendly command-line tools.
Relevant interview questions
Here are some interview questions to help you assess a potential Golang freelancer:
- Describe your experience with Golang's concurrency model.
- What are the advantages and disadvantages of using goroutines?
- Explain how you would handle error management in a Golang project.
- Walk me through your experience with testing in Golang.
- Describe a challenging Golang project you worked on and how you overcame the difficulties.
Tips for shortlisting candidates
To effectively shortlist candidates, consider these tips:
- Review portfolios and code samples: Assess the quality and complexity of their previous work.
- Conduct technical assessments: Use coding challenges or take-home assignments to evaluate their practical skills.
- Check references: Speak to previous clients to gain insights into their work ethic and reliability.
- Assess communication skills: Pay attention to their responsiveness and clarity during the initial interactions.
Potential red flags
Be mindful of these potential red flags:
- Lack of demonstrable experience: Be wary of candidates who cannot provide concrete examples of their Golang work.
- Poor communication: Unclear or evasive responses can indicate potential communication challenges.
- Unrealistic timelines or cost estimates: Ensure their estimations align with the project's scope and complexity.
Typical complementary skills
Golang developers often possess complementary skills such as:
- Database management (PostgreSQL, MySQL, MongoDB): Essential for backend development.
- Cloud platforms (AWS, Google Cloud, Azure): Crucial for deploying and managing applications.
- Containerisation (Docker, Kubernetes): Important for building and deploying scalable applications.
- API design and development (REST, GraphQL): Crucial for building modern web applications.
