Preparing for Coding Interviews

When it comes to coding interviews, preparation is key. In this article, we will explore different strategies to help You excel in your coding interviews. While algorithms play a significant role in these interviews, there are clever ways to prepare that go beyond simply memorizing code. We will discuss the infamous list of 75 leaked code questions, the difficulty of coding problems, organizing problem types, and leveraging online resources.

The List of 75 Leaked Code Questions

The 75 leaked code questions originated from a Facebook tech lead who compiled the most comprehensive and helpful questions from a larger pool. These questions cover a wide range of patterns that frequently appear in coding interviews. While it may seem appealing to solve all 75 questions, it's important to note that some of them can be extremely difficult. For example, the Word Search 2 problem is notorious for its complexity and time constraints.

Memorizing Patterns vs. Code

Instead of trying to memorize every line of code for each question, it is more efficient to focus on memorizing patterns. By understanding the underlying patterns and algorithms, you can approach similar problems more effectively. For example, instead of recalling specific code for Word Search 2, you could memorize a high-level approach involving a hashmap and index tracking. This strategy allows you to adapt and solve various questions without getting overwhelmed by code details.

Organizing Problem Types

To further enhance your preparation, it is beneficial to group similar problems together. By categorizing problems Based on their types, such as arrays, dynamic programming, or tree-related questions, you can identify common patterns among them. This approach enables you to leverage your understanding of specific algorithms and problem-solving techniques across multiple questions. For instance, recursive depth-first search algorithms are frequently used in tree-related questions.

Leveraging Online Resources

Online platforms like LeetCode offer a wealth of resources that can aid in your preparation. The Discuss section provides valuable insights shared by other developers, including detailed discussions and problem-solving approaches. Additionally, the Interview Questions section offers information about specific companies and the questions they commonly ask. Although the accuracy of user-generated content varies, it serves as a useful resource to gain insights into a company's preferred interview topics or data structures.

Conclusion

Preparing for coding interviews requires a combination of understanding algorithms, memorizing patterns, organizing problem types, and leveraging online resources. By adopting these strategies, you can enhance your problem-solving abilities and increase your chances of success in coding interviews. Remember, becoming a coding interview expert doesn't require being a genius; it demands dedication, practice, and a systematic approach to learning.
