• Language Limitations
  While Codility supports multiple programming languages, some niche or less commonly used languages may not be available.
• Potential Stress for Candidates
  Automated assessments can induce stress for candidates, which might not accurately reflect their true abilities in a real-world setting.
• Internet Connection Dependency
  A stable internet connection is required to complete assessments, which can be a limitation in areas with unreliable internet access.
• Limited Collaboration Features
  Codility's focus on individual assessments means it has limited support for evaluating collaborative or team-based coding skills.
• Algorithm Focus
  The platform often emphasizes algorithmic problem-solving, which may not fully represent the day-to-day coding skills required for certain positions.

• Static Code Analysis
  Credo provides static code analysis for Elixir, which helps developers identify potential issues in their code without executing it.

Possible disadvantages

• Configuration Complexity
  Setting up and configuring Credo for the first time can be complex, especially for teams unfamiliar with Elixir.
• Overhead
  Running static analysis tools like Credo can add overhead to the development process, especially in large projects.
• Learning Curve
  There can be a learning curve for new users to fully understand and effectively utilize all of Credo's features and options.
• False Positives
  As with many static analysis tools, Credo might occasionally report false positives that can require time to review and address.
• Limited to Elixir
  Credo is specific to the Elixir programming language, so its benefits do not extend to other languages within multi-language projects.
