In software and engineering fields, technical interviews include stages beyond standard behavioral questions that measure coding, system design, or technical problem-solving skills. This article covers how to prepare for this format. For general interview preparation, see How to Prepare for a Job Interview.
What Does a Technical Interview Usually Consist Of?
- Coding questions: You're asked to code a specific problem live (usually while sharing your screen).
- System design: For more senior positions, you're asked how you'd design a large-scale system.
- Discussion of past projects: You may be asked to discuss a project from your resume in depth (see How to Add a Projects Section to Your Resume).
Preparing for Coding Questions
- Review core data structures and algorithms. Topics like arrays, linked lists, trees, and basic search/sort algorithms come up often.
- Think out loud. Instead of coding silently, walk through your approach step by step — the interviewer wants to see your process.
- Summarize your approach before you start coding. Instead of jumping straight into code, briefly saying "I'll try this approach because..." clarifies your thought process.
- Test your code. After writing it, check its logic with a few sample inputs.
Preparing for System Design Questions
- Start by clarifying requirements. Starting by asking how many users the system needs to support, what data volume, and what constraints exist shows a structured approach.
- Move from the big picture to the details. Sketch the overall architecture first, then detail the critical components.
- Discuss trade-offs. Every design decision involves a trade-off; stating these explicitly shows engineering maturity.

Build Your Resume FreePreparing to Discuss Past Projects
For every technical project on your resume, prepare to describe the challenge you faced, the decisions you made, and the outcome using the STAR technique. You should also be able to explain why you chose the technologies you used.
If You Run Into a Question You Don't Know
Admitting you don't know something is far better than pretending you do and giving a wrong answer. Saying "I'm not entirely sure about this, but here's an approach I'd try..." shows both honesty and your problem-solving approach.
Conclusion
Success in a technical interview comes not just from knowing the right answer, but from clearly communicating your thought process. Reviewing core concepts, thinking out loud, and being able to discuss your past projects in detail let you deliver a strong performance in this format.
