How to Prepare for Coding Interviews 

My Weekly Plan

Introduction

Preparing for coding interviews can feel overwhelming — data structures, algorithms, system design, aptitude, and HR rounds all at once!
But with a clear plan, you can make consistent progress and feel confident before any interview.

In this post, I’ll share a 7-day structured weekly plan that helps you stay focused and cover everything effectively — from problem-solving to mock interviews.

7-Day Coding Interview Preparation Plan

Day 1: Understand the Interview Pattern

Start by learning what to expect in a coding interview.
  Common rounds include:

  • Online coding test

  • Technical interview (DSA & logic questions)

  • HR/Behavioral interview

Task for the Day:

  • Research your target companies (TCS, Infosys, Wipro, etc.)

  • Read about their previous interview patterns on websites like GeeksforGeeks or Glassdoor.

Day 2: Revise Core Data Structures

Focus on foundational data structures:

  • Arrays

  • Linked Lists

  • Stacks

  • Queues

  • Trees

  • Hash Maps

Task for the Day:

  • Practice 10 questions on arrays and linked lists.

  • Understand when to use which data structure.

Tip: Don’t just memorize — visualize how data moves inside structures.

Day 3: Practice Sorting & Searching Algorithms

Core algorithms are frequently asked.
Study and implement:

Task for the Day:

Day 4: Learn Problem-Solving Techniques

This day is all about pattern recognition and logic building.
Focus on:

  • Recursion

  • Dynamic Programming (start simple like Fibonacci)

  • Sliding Window Technique

Task for the Day:

  • Solve 3 medium-level problems on recursion and DP.

  • Read editorial solutions for better understanding.

Day 5: Work on Real Interview Questions

Now test your progress with real coding challenges.

Task for the Day:

Tip: Focus on clarity — write clean, readable code and add comments.

Day 6: Mock Technical Interview

Simulate a real interview environment.

Task for the Day:

  • Ask a friend or use tools like Pramp or InterviewBuddy for mock interviews.

  • Practice explaining your code aloud.

Tip: Confidence matters as much as correctness.

Day 7: HR & Soft Skills Practice

Coding alone isn’t enough — interviewers also test communication, teamwork, and attitude.

Task for the Day:

  • Prepare short answers for common HR questions:

    • Tell me about yourself

    • Strengths and weaknesses

    • Why should we hire you?

  • Practice speaking fluently in front of a mirror or record yourself.

Conclusion

This 7-day plan is your repeatable weekly structure — cycle through it every week, increasing problem difficulty and speed each time.

In just a few weeks, you’ll notice:
* Better problem-solving confidence
* Stronger logic-building ability
* Improved communication for interviews

Keep learning, stay consistent, and success will follow!
