Hello Vijay Singh,

You’ve got 8 years of solid experience in C++ and Python — that’s a great base!

To switch companies, follow this:

▪️ Quick Prep Plan:

1. DSA Practice – Leetcode daily (focus on arrays, trees, DP).

2. System Design – Learn low-level & high-level design (YouTube: Gaurav Sen).

3. Resume – Highlight impact, not just roles. Keep it 1 page.

4. Mock Interviews – Practice with friends or online platforms.

5. Company Research – Check what each company focuses on (Glassdoor, Leetcode Discuss).

Switching companies after 8 years is a great opportunity to grow and explore new challenges. Since you already have solid experience in C++ and Python, here’s how you can effectively prepare for interviews:

1. Update Your Resume & LinkedIn

• Highlight key projects, achievements, and leadership roles.
• Emphasize impact—e.g., "Optimized system performance, reducing processing time by 30%" instead of just "Worked on system optimization."

2. Master Data Structures & Algorithms

• Since many tech interviews focus on DSA, practice on platforms like Leetcode, Codeforces etc.
• Focus on key topics: Trees, Graphs, Dynamic Programming, and Multithreading (for C++).

3. System Design & Low-Level Design (LLD)

• Senior roles often involve designing scalable systems. Study design patterns, microservices, and concurrency models.
• Read "Designing Data-Intensive Applications" & "System Design Interview"

4. Brush Up on C++ & Python Advanced Concepts

• C++: Memory management, multithreading, smart pointers, STL deep dive.
• Python: Asynchronous programming, OOPs, and performance optimization techniques.

5. Mock Interviews & Behavioral Rounds

• Practice STAR (Situation, Task, Action, Result) format for HR & leadership rounds.
• Conduct mock interviews with peers or professionals on platforms like Preplaced

6. Target the Right Companies & Apply Strategically

• Identify companies aligned with your career goals—startups vs. big tech vs. fintech, etc.
• Use referrals (LinkedIn connections, ex-colleagues, alumni).
