A technical interview measures not only whether you know the answer, but how you think and communicate under pressure. Good preparation balances reviewing fundamentals with practicing thinking aloud.
Review the Fundamentals First
- Common data structures and algorithms.
- Concepts of the language or framework you'll be interviewed on.
- System-design basics if the role is more senior.
A Problem-Solving Approach
- 1Restate the question to confirm your understanding.
- 2Ask about edge cases and assumptions.
- 3Explain your plan before writing code.
- 4Implement, then test with a small example.
The interviewer evaluates your thinking as much as your answer, so always think out loud.
💡 Pro Tip
Run a mock interview to get used to explaining your thinking under time before the real one.
