Coding Interview Prep Questions là gì
Coding interview prep is the practice of solving algorithm problems to pass technical interviews at software companies. Companies like Google, Amazon, Meta ask candidates to solve data structure + algorithm problems on whiteboard/CodeSignal, optimizing for time and space complexity. Success requires pattern recognition, intuition, and speed. Core topics:
🔧 CÔNG CỤ & HỆ SINH THÁI
LeetCode.com (premium, ~$160/year)HackerRank.comCodeSignal (Codesignal assessments used by companies)Interviewing.io (mock interviews)Blind 75 (curated list)System design primers (Grokking System Design)Python/JavaScript for codingWhiteboard simulators (Zoom-based mock)

🎯 Sự Nghiệp Sử Dụng Coding Interview Prep Questions
❓ Câu hỏi thường gặp
How many problems to solve?
50 → comfortable, 100 → confident, 200 → interview-ready. Diminishing returns after 200; quality > quantity.
Which language?
Python most popular (concise, fast to code). Java, Go also common. Pick one you're comfortable with.
LeetCode vs HackerRank?
LeetCode = broader range, harder problems, more company-specific curations. HackerRank = tutorial-rich, good for learning. Start HackerRank, graduate to LeetCode.
Do interviews really ask LeetCode?
Yes, FAANG and well-funded startups ask. Smaller companies less so. Prep covers 80% of interview questions; 20% novel.
Time investment?
3 months full-time (8 hrs/day), or 6 months part-time (2 hrs/day). Depends on baseline algo knowledge.
System design?
Software engineer > 3 yrs: expect system design questions (design Uber, Twitter, etc.). Learn separately from data structures.
Salary impact?
Interview pass rate → better companies → 30–50% salary increase. Not a salary skill per se, but gate to high-paying roles.
