Statistic:According to a 2020 survey by CodinGame, 54% of technical interviews focused on algorithms and data structures.
Time and Space Complexity: Know how to analyze and optimize the efficiency of your code using Big O notation.
System Design: For more senior roles, expect questions related to system architecture, scalability, and system trade-offs.
3. Practice Coding Problems
LeetCode, HackerRank, and CodeSignal: Use these platforms to practice coding problems.
Statistic:In a 2021 survey by HackerRank, 80% of developers said they used online platforms to practice coding.
Whiteboard vs. Online Coding: Be comfortable coding on a whiteboard or shared document as well as on a computer.

4. Mock Interviews
