Possible disadvantages of LeetCode

• Paid Subscription
  While LeetCode offers many resources for free, a premium subscription is required to access some advanced features, company-specific questions, additional test cases, and certain problem solutions.
• Steep Learning Curve
  For beginners, the wide range of problem difficulties and the complexity of some problems can be intimidating and may require a significant amount of time and effort to get up to speed.
• Limited Technology Coverage
  LeetCode mainly focuses on algorithm and data structure problems and doesn't cover other technical aspects like system design, databases, or front-end development as comprehensively.
• Variable Quality of Community Solutions
  While the community is active, the quality of user-contributed solutions and explanations can vary significantly, and some may not follow best practices or be optimal.
• Platform Performance Issues
  Some users report occasional performance issues such as slow loading times or glitches during peak usage times, which can be frustrating during practice or contests.
• Overemphasis on Coding
  LeetCode's focus is predominantly on coding problems, which might lead some users to neglect other important skills required for technical interviews, such as communication and problem-solving in real-world scenarios.
