Preparing for tech interviews is not just about solving 100 LeetCode problems. It’s about understanding core concepts, practicing communication, and building confidence in problem-solving under pressure.
🧠 Data Structures & Algorithms First
I start by mastering topics like arrays, strings, linked lists, stacks, queues, trees, graphs, dynamic programming, and sorting algorithms. I use platforms like LeetCode, GeeksforGeeks, and NeetCode roadmap.
🛠️ Real Practice: Mock Interviews
Practicing mock interviews with friends or platforms like Pramp helps reduce nervousness. I simulate 45-minute interviews where I speak out loud while solving.
📚 CS Fundamentals Matter
I make sure I’m clear on DBMS, OS, Networking, and OOP — the usual theory rounds. I revise through short notes and YouTube revision videos 1–2 days before an interview.
💬 Behavioral & HR Prep
I practice common HR questions like “Tell me about yourself,” “What’s your strength/weakness?”, and “Describe a challenge you overcame.” I keep answers structured, honest, and example-based.
🎯 My Weekly Interview Routine
- 🧩 1–2 DSA problems daily (medium-level)
- 📘 Revise 1 CS concept every other day
- 💻 Weekly mock interview
- 📄 Resume & projects polish (ongoing)
Interviews test how well you can think and communicate. Being calm, clear, and consistent matters more than brute force. Just focus on improving every day.
