  While Codility supports multiple programming languages, some niche or less commonly used languages may not be available.
• Potential Stress for Candidates

• 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.

Select Star SQL features and specs

• Completely Free
  Select Star SQL is entirely free to use with no paywalls, subscriptions, or hidden costs. This makes it accessible to anyone who wants to learn SQL regardless of their financial situation.
• Interactive Hands-On Learning
  The platform provides an interactive SQL environment directly in the browser where learners can write and execute real SQL queries against actual datasets, reinforcing concepts through practice rather than passive reading.
• Real-World Dataset
  The course uses a compelling real-world dataset about Texas death row executions, which makes the learning experience more engaging and meaningful compared to abstract or contrived examples.
• Well-Structured Progressive Curriculum
  The course is organized in a logical progression from basic SELECT statements to more advanced concepts like aggregations, joins, and subqueries, allowing learners to build knowledge incrementally without feeling overwhelmed.
• No Setup Required
  There is no need to install any software, set up a database, or configure an environment. Learners can start writing SQL queries immediately in their web browser, removing a significant barrier to entry for beginners.

Possible disadvantages of Select Star SQL

• Limited Scope
  The course covers only fundamental SQL concepts and does not address more advanced topics like window functions, CTEs, indexing, database design, or performance optimization, which are essential for professional SQL usage.
• Single Database Dialect
  The platform teaches SQL using SQLite, and does not cover syntax differences or features specific to other popular database systems like PostgreSQL, MySQL, SQL Server, or Oracle, which learners may encounter in real jobs.
• No Certificate or Credential
  Completing the course does not provide any formal certificate, badge, or credential that learners could use to demonstrate their SQL skills to potential employers or on professional profiles.
• Limited Practice Exercises
  While the course includes some exercises, the total number of practice problems is relatively small compared to dedicated SQL practice platforms, which may not be sufficient for learners who need extensive repetition to solidify their skills.
• Single Dataset Can Feel Restrictive
  Using only one dataset throughout the entire course means learners do not get experience working with diverse data schemas, table relationships, or different types of data, which limits exposure to varied real-world scenarios.
