Caching strategies
About this practice interview
A hard-level Backend mock interview that runs about 30 minutes as a conversation session. Scenario-driven questions on cache correctness. The AI interviewer asks follow-up questions based on what you actually say, so each attempt plays out differently. When you finish, you get a report with a readiness score, question-by-question feedback, and the areas to work on next.

How it works

Do I need a microphone?
Only for voice mode. In chat mode you type your answers instead, and you can switch between the two at any point mid-interview.
How is my interview scored?
The interviewer scores each answer against the skills this interview covers (TTL, Invalidation, CDN). At the end you get a report with an overall readiness score, per-question feedback, strengths, and focus areas.
Can I retake the interview?
As many times as you want. Follow-up questions depend on what you say, so no two attempts play out the same, and each report compares your score with your previous attempt.
