Key takeaways
- Know the problem Server Actions Overview solves before memorizing APIs
- Prefer a tiny demo you can rewrite from memory

Common mistakes
- Memorizing definitions without writing a demo
- Ignoring edge cases interviewers always probe
- Copying patterns without knowing performance or a11y cost
Interview angle
Be ready to define Server Actions Overview in one or two sentences, show a small example, and name one tradeoff. Clear models beat jargon dumps.
Practice
