How should I revise DevOps topics effectively in 2–3 days before an interview?

Hi everyone,

I am currently preparing for DevOps Engineer interviews and often get only 2–3 days between interview rounds. Due to limited time, I find it difficult to revise all important topics effectively.

I would really appreciate your guidance on:

  • How to quickly revise key DevOps topics (AWS, Kubernetes, Linux, Networking, CI/CD)
  • Best strategy to revise concepts vs hands-on practice in a short time
  • How to prepare for troubleshooting and scenario-based questions
  • Any tips for creating quick revision notes or cheat sheets

If you have any proven strategy or personal experience, please share — it would be very helpful.

Thanks in advance!
