💼 Here’s how I’d prepare for Coding Interviews FAST if I had to start from zero:

1) Learn one language deeply.
Pick Python, Java, or C++ — all are widely accepted in interviews.
Stick to one and master syntax, data structures, and problem-solving.

2) Understand time & space complexity.
Learn how to analyze your code using Big O Notation.
This is key to optimizing solutions and impressing interviewers.

3) Master data structures.
Focus on:
– Arrays & Strings
– Linked Lists
– Stacks & Queues
– Hash Maps
– Trees & Graphs
Build visual intuition and practice implementation.

4) Practice algorithms daily.
Start with:
– Sorting & Searching
– Recursion
– Two Pointers
– Sliding Window
– Dynamic Programming
Use platforms like LeetCode, Codeforces, or InterviewBit.

5) Use problem-solving patterns.
Learn reusable strategies like:
– Divide & Conquer
– Backtracking
– Greedy
– BFS/DFS
– Memoization
Patterns help you solve new problems faster.

6) Build a cheat sheet.
Document common patterns, syntax tricks, and edge cases.
Review it before every mock interview.

7) Simulate real interviews.
Use mock platforms or pair up with friends.
Practice whiteboard-style explanations and think aloud.

8) Learn system design basics.
Even for junior roles, understanding scalability, APIs, and architecture helps.
Start with:
– Load Balancing
– Caching
– Database Design
– RESTful APIs

9) Prepare behavioral answers.
Use the STAR method to structure responses.
Practice answers for:
– Strengths/Weaknesses
– Conflict resolution
– Teamwork & leadership

🔟 Track progress & stay consistent.
Use a spreadsheet or Notion board to log solved problems, topics covered, and weak areas.
Consistency beats cramming.
