How to crack coding test?

Master the Fundamentals

Data Structures and Algorithms

Understanding data structures like arrays, linked lists, stacks, queues, trees, and graphs is crucial. Equally important are algorithms such as sorting, searching, recursion, and dynamic programming. These fundamentals form the backbone of solving coding problems efficiently.

Practice Coding Problems

Solve Regularly

Dedicate 2-4 hours daily to solving coding problems on platforms like LeetCode, HackerRank, or CodeSignal. Consistent practice helps reinforce your understanding and improves your problem-solving speed.

Focus on Coding Patterns

Identify and master common coding patterns such as:

• Sliding Window
• Two Pointers
• Fast and Slow Pointers

Recognizing these patterns can help you quickly identify solutions during the test.

Simulate the Test Environment

Timed Practice

Take practice tests under timed conditions to mimic the pressure of the actual coding test. This helps you manage your time effectively and stay calm under stress.

Mock Interviews

Participate in mock interviews to get accustomed to the interview format. DesignGurus.io offers Coding Mock Interview sessions that provide personalized feedback from experienced engineers.

Optimize Your Solutions

Improve Efficiency

After solving a problem, review your code to find ways to make it more efficient. Focus on optimizing both time and space complexity to demonstrate your ability to write clean and effective code.

Communicate Effectively

Explain Your Thought Process

During the test, clearly articulate your reasoning and approach. This not only helps you stay organized but also showcases your problem-solving skills to the evaluator.

Review and Learn from Mistakes

Analyze Your Performance

After each practice session or mock test, review the problems you struggled with. Understand your mistakes and learn the correct approaches to avoid repeating them in the future.

Stay Healthy and Confident

Balanced Routine

Maintain a healthy balance between coding practice and other activities. Ensure you get enough sleep, eat well, and take regular breaks to keep your mind sharp and focused.
