Coding Interview Preparation Phases

Crawl Phase

Step 1 : Basic Concepts

Learn the basic data structures and algorithms. Learn the basic concepts and terminology to build your vocabulary of programming.

Step 2 : Code

Code the representation and operations for the data structures in your list.

Step 3 : Coding Drills

Design coding drills and practice the algorithms in your list.

Step 4 : Analyze

Analyze the time and space complexity of your code.

Step 5 : Test

Test your code using test cases. Debug and fix any bugs.

Step 6 : Take Notes

Take notes to help you review later. Learn from your mistakes.

Step 7 : Pros and Cons

After you have learned about the data structures in your list, compare the pros and cons of using similar data structures.

Walk Phase

Step 1 : Understand the Problem

Understand the problem statement before you design the algorithm.

Step 2 : Identify the Approach

Identify the data structure, algorithm and strategy to solve the problem.

Step 3 : Outline the Solution

Outline the solution at a high level.

Step 4 : Identify the Obstacles

Identify the obstacles to solving the problem. Revisit your study materials to gain a deeper understanding of the concepts. This is a top down approach to assimilation process.

Step 5 : Work Backwards

Work backwards from the solution. Design and practice coding drills. Practice coding the solution and understand the solution. This is a bottom up approach to assimilation process.

Step 6 : Test

Test your code with test cases.

Step 7 : Analyze

Analyze the time and space complexity of your solution.

Step 8 : Take Notes

Review your solution and reflect. Take notes on where you made mistakes and review your solution.

Run Phase

Step 1 : Form Links

Connect the dots between problems you solved in walk phase.

Step 2 : Problem Types

Solve problems by category.

Step 3 : Recognize Patterns

Summarize common patterns used for solving problems within the same category.

Step 4 : Take Notes

Take notes on where you made mistakes to help you review later.

Step 5 : Practice

Practice articulating your solution.

Step 6 : Evaluate Progress

Form a study group. Take mock interviews.
