Name a time you ran into a problem and solve it, and talk through your resume and personal experiences to gauge your technical background. Choose a specific technical problem you personally encountered, explain the context and constraints, and walk through how you diagnosed and resolved it. Be prepared to connect your decisions to relevant experiences on your resume, including what you owned, how you collaborated, and what changed as a result.
