How do I prepare for a software engineer interview?
Software engineer interviews usually come in four parts: a coding test, a technical interview, system design, and a project or behavioral round. Each looks for something different, so check the company's process first and be ready to explain the projects on your resume in depth. Follow-up questions about your own projects are where answers most often fall apart.
What each round looks for
- Coding test: how quickly and correctly you turn a problem into a solution. In live coding, whether you explain your thinking out loud.
- Technical interview: fundamentals of your language and framework, databases and networking, and why things work the way they do
- System design: asking about requirements, assuming a scale and sketching an architecture. The reasons for your choices and what you gave up matter more than a right answer. Common for experienced hires.
- Project and behavioral round: what you owned in the projects on your resume, hard decisions, incidents, working with others
How to prepare
- For each project on your resume, write one page: the problem, what you did, the result in numbers, and what you'd change next time.
- For each technology you used, be ready to say why you chose it and what the alternatives were.
- Match the stack and requirements in the job posting to your own experience.
- Practice live coding out loud, even when you're solving problems alone.
Practicing with SpeechShield
Add your resume and the job posting to an interview context and do a video mock interview with a friend: talking points follow up on your earlier answers and your resume. Asked about something not on your resume, it suggests saying you haven't done it and explaining how you'd approach it.
Put a coding problem on screen and press ⌘K to attach it for an explanation with code. Choose the programming language in Settings → Code Assistant. Real coding tests often have their own AI policy, so use it only where it's allowed.

How do new-grad and experienced interviews differ?
New-grad interviews ask more about fundamentals, how you learned, and personal or team projects. Experienced interviews dig deeper into decisions on real services, incidents and system design.
What if they ask about a technology I don't know?
Say you haven't used it instead of bluffing, and talk about similar experience or how you'd learn it. That beats falling apart on the follow-up.
