2. Timeframe Preparation

The amount of time you have before your interview can significantly impact your preparation. Here’s how to adapt your study plan based on your timeframe:

1 Month Preparation

Weeks 1-2: Focus on coding problems and algorithms. Practice on platforms like LeetCode and HackerRank. Week 3: If applying for a senior position, practice system design challenges. Resources like ExpertSysDesign can help you with these. Week 4: Conduct mock interviews and focus on behavioral questions. Platforms like Pramp and are great for this.

2-3 Months Preparation

Month 1: Dive deep into data structures and algorithms. LeetCode, HackerRank, and CodeSignal offer extensive practice. Month 2: Focus on system design and behavioral questions. Use resources like ExpertSysDesign and GeeksforGeeks. Month 3: Conduct mock interviews and review feedback. Use platforms like Pramp or to get practice and constructive feedback.

3. Core Topics to Study

To be well-prepared, focus on the following core topics:

Data Structures

Arrays Linked Lists Stacks Queues Trees Graphs Hash Tables

Algorithms
