You want to ace your next technical interview. Coding tests feel hard. A solid practice plan helps.
Focus on these core areas.
- Array and string manipulation.
- Object data structures.
- Recursion and algorithms.
- Async and promises.
- DOM and browser APIs.
Use this process to solve problems.
- Read the requirements.
- Define input and output.
- List edge cases.
- Write a simple solution first.
- Optimize the time and space complexity.
Know your Big O notation.
- O(1): Constant.
- O(log n): Logarithmic.
- O(n): Linear.
- O(n log n): Linearithmic.
- O(n squared): Quadratic.
Consistent practice beats memorizing solutions.
