🔥 REAL INTERVIEW QUESTIONS ASKED – DEVOPS ENGINEER
📌 TECHNICAL ROUND (12 Qs)
Q1. Explain how you would set up and manage a hybrid cloud infrastructure using both AWS and GCP.
Candidate Answer:
"I’d start with assessing which workloads go on AWS and which on GCP. For instance, I might run latency-sensitive apps on GCP and storage-heavy on AWS S3.
