Possible disadvantages

• Cost
  Codility can be relatively expensive, especially for small companies or startups with limited recruitment budgets.
• Learning Curve
  There might be a learning curve for both recruiters and candidates to get accustomed to the platform and its features.
• 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.
