LeetCode vs Real Coding Interviews: A Comparison for 2024

Written by

Netizens

Ever feel the pressure to perform well in a technical interview?  Many companies rely on coding assessments to evaluate a candidate’s problem-solving abilities. This is where LeetCode comes in.

What is LeetCode?

LeetCode is an online platform designed to help individuals improve their coding skills, prepare for technical interviews, and participate in competitive programming. It offers a vast collection of coding problems that span various topics, such as algorithms, data structures, databases, and shell scripting. The platform is widely used by software engineers and developers to practice and hone their problem-solving abilities.

Key Features of LeetCode

  • Extensive Problem Library: LeetCode hosts over 2000 problems, categorized by difficulty (Easy, Medium, Hard) and topic (Arrays, Linked Lists, Dynamic Programming, etc.). This allows users to focus their practice on specific areas they wish to improve.
  • Real-World Relevance: Many problems on LeetCode are inspired by actual interview questions from leading tech companies like Google, Facebook, Amazon, and Microsoft. This makes it a practical tool for job seekers preparing for technical interviews.
  • Active Community: The platform has a vibrant community of users who discuss problems, share solutions, and provide insights. Engaging with this community can offer different perspectives and techniques for problem-solving.
  • Coding Contests: LeetCode organizes regular contests and competitions that simulate real interview conditions. These contests help users test their skills under time constraints and improve their performance in competitive settings.
  • Mock Interviews: LeetCode’s mock interview feature allows users to simulate a real interview environment. This feature pairs users with a set of problems and a timer, mimicking the experience of a live coding interview.
  • Premium Subscription: While LeetCode offers a free tier, a premium subscription provides access to additional problems, company-specific problem sets, and detailed interview experiences from other users.

How to Use LeetCode?

  1. Create an Account: Sign up for a free account on LeetCode. Consider a premium subscription for access to exclusive problems and detailed interview experiences from other users.
  2. Understand the Problem Categories: Problems on LeetCode are categorized by difficulty (Easy, Medium, Hard) and topic (Arrays, Linked Lists, Dynamic Programming, etc.). Familiarize yourself with these categories to target your practice effectively.
  3. Start with Easy Problems: If you’re new to coding or LeetCode, begin with easy problems to build confidence and understanding of the platform.
  4. Read Discussions and Solutions: After attempting to solve a problem, review the discussions and solutions provided by the community. This can expose you to different ways of thinking and problem-solving techniques.
  5. Use the Progress Tracker: LeetCode’s progress tracker helps you monitor your performance over time. Use this feature to keep track of your progress and adjust your study plan accordingly.
  6. Participate in Contests: Regular participation in LeetCode contests will help you get accustomed to solving problems under time constraints and improve your ranking in the community.
  7. Simulate Interview Conditions: Use the mock interview feature to practice solving problems under timed conditions. This practice can help you manage time effectively during actual coding tests.

How to solve leetcode problems?

  • Consistency is Key: Dedicate a specific amount of time each day or week to solving problems. Consistency will help you build and retain your skills over time.
  • Focus on Weak Areas: Identify topics where you struggle the most and prioritize practicing those areas. LeetCode allows you to filter problems by topic, making it easier to target your weaknesses.
  • Review and Reflect: After solving a problem, review your solution and compare it with others. Reflect on what you did well and where you can improve.

Leveraging LeetCode for Interviews

  1. Company-Specific Preparation: LeetCode allows you to filter problems by company, which can be immensely helpful if you’re preparing for an interview with a specific organization. Focus on frequently asked problems by that company. 
  2. Track Your Progress: LeetCode’s progress tracker helps you monitor your performance over time. Use this feature to keep track of your progress and adjust your study plan accordingly.

Conclusion

LeetCode is an invaluable resource for anyone looking to enhance their coding skills and succeed in technical interviews. By leveraging its extensive problem library, engaging with the community, and practicing consistently, you can significantly improve your problem-solving abilities and increase your chances of landing your dream job. Happy coding!
