• Complete basic programming courses on HackerRank, CodeChef, or Udemy.
• Read “Let Us C” by Yashavant Kanetkar or follow CS50 by Harvard (for Python).
• Solve beginner problems on HackerRank, CodeStudio, and LeetCode.
• Participate in college-level hackathons and coding contests.
• Build small projects like calculators, to-do apps, or games to apply your coding skills.

2nd Year: Diving into Data Structures & Algorithms (DSA)

Focus Areas:

• Learn advanced DSA: Trees, Graphs, Dynamic Programming, Greedy Algorithms.
• Competitive Coding basics and time complexity analysis.

Action Plan:

• Study from “Data Structures and Algorithms Made Easy” by Narasimha Karumanchi.
• Complete GeeksforGeeks DSA Self-Paced Course.
• Start solving problems on Codeforces, CodeChef, and AtCoder.
• Join open-source projects on GitHub to gain practical experience.
• Participate in Google Kick Start, Facebook Hacker Cup, and local hackathons.

3rd Year: Mastering Competitive Coding & Internships

Focus Areas:

• Master competitive coding techniques.
• Apply for internships and start interview preparation.

Action Plan:

• Solve medium-to-hard problems on LeetCode, Codeforces, and AtCoder.
• Participate in ICPC, CodeChef Long Challenge, and Hackathons.
• Apply for internships via Internshala, AngelList, and LinkedIn.
• Learn System Design basics and practice behavioral interview questions.
• Contribute to major open-source projects to build your profile.

4th Year: Placement Preparation & Advanced Learning

Focus Areas:

• Advanced competitive coding and interview preparation.
• Applying for full-time roles at top tech companies.

Action Plan:

• Daily problem-solving on LeetCode, Codeforces, and CodeChef.
• Revise DSA and System Design thoroughly.
• Apply to tech companies through coding competitions like TCS CodeVita, Google Code Jam, and LinkedIn.
• Prepare for HR and behavioral rounds.
