How to prepare for coding interviews…
Here is the day-wise roadmap to follow:
✅Build a strong foundation
(WEEKS 1-4)
🎯Focus on the most frequently asked topics.
🎯Resources:
Neetcode 150 for a structured problem set.
Cracking the Coding Interview:
Chapters 1-4 for basics.
Take U Forward (YouTube): Great explanation for each video.
✅Practice Problems Strategically
(WEEKS 5-12)
🎯Tackle problems in three stages:
Stage 1: Solve 50 easy problems to get comfortable.
Stage 2: Solve 75 medium problems, focusing on optimization.
Stage 3: Solve 15 hard problems if targeting FAANG.
🎯Platforms to Practice:
LeetCode: Sort by difficulty or tags (arrays, DP). and contests
HackerRank: For warm-ups and hirimg contests.
✅Master Core Algorithms and Data
Structures
(WEEKS 13-16)
🎯Key Focus Areas:
Binary Search: Search in rotated arrays, peak elements.
Recursion and Backtracking:
Subsets, permutations, Sudoku solver.
Dynamic Programming:
Classic problems like Fibonacci,
Knapsack, LIS.
Understand bottom-up and top-down approaches.
Trees and Graphs:
BFS/DFS traversal, shortest path (Dijkstra).
🎯Resources:
Neetcode Playlists: Trees, DP, and
Graphs.
Tushar Roy YouTube Channel:
Algorithm deep dives.
LeetCode Discussion Forums:
Optimized solutions and hints.
✅Learn System Design Basics
(WEEKS 17-20)
🎯Resources:
System Design Primer (GitHub):
Beginner to advanced.
Grokking the System Design Interview: Simplified concepts.
Designing Data-Intensive
Applications: Real-world system insights.
✅Mock Interviews and
Communication
(WEEKS 21-24)
🎯 Use platforms:
Pramp: Peer-to-peer interviews.
InterviewBit: Mock interviews with industry experts.
Record yourself solving problems and analyze
✅Behavioral Questions
(ONGOING)
🎯How to Prepare:
Use the STAR method: Situation, Task,
Action, Result.
Focus on stories that highlight leadership, impact, and learning.
Mock practice with peers or record yourself.
🎯Resources:
Big Interview (Behavioral Prep):
Comprehensive practice.
Google common behavioral interview questions.
