Software Engineer Mock Interview Questions (with Prep Tips)
Common behavioral and technical prompts for SWE interviews—and how to practice with AI scoring.
Behavioral questions to prepare
Tell me about a challenging project and your role.
Describe a time you disagreed with a teammate—how did you resolve it?
Walk me through a production incident you helped fix.
Answer each with STAR and numbers where possible.
Technical and system design
Expect fundamentals: data structures, APIs, databases, testing, and tradeoffs. Senior roles add system design: scalability, consistency, and failure modes.
Practice explaining your thinking out loud; interviewers score communication as much as the final architecture.
