Tech Presentation Interview

The tech presentation round is a reverse system design: instead of designing a hypothetical system on a whiteboard, you present a real system YOU built. This tests three things no other round can: genuine depth of understanding, ability to communicate complex ideas under pressure, and authentic ownership versus inherited knowledge.

When to Use

Use for:

• Selecting which project to present from your career
• Structuring a 25-45 minute technical presentation with narrative arc
• Calibrating depth -- which components to go deep on, which to skim
• Preparing whiteboard/virtual-board diagrams with progressive disclosure
• Rehearsing answers to hostile follow-up questions
• Adapting presentation to different audience compositions (researchers, engineers, managers)
