• Advanced concepts (less common) – Zero-trust network architectures, BGP routing protocols, and advanced intrusion detection systems.

Example questions or scenarios:

• "Walk me through the exact path a packet takes from a user's browser, through our cloud firewalls and load balancers, to a microservice running in a private subnet."
• "What methods and tools would you implement to ensure that developer access to production databases is fully secure, audited, and compliant with data privacy regulations?"

Data Structures & Algorithms (DSA)

We believe that strong software engineering fundamentals make better DevOps engineers. You will face coding challenges designed to test your algorithmic thinking and scripting efficiency.

Be ready to go over:

• Core Data Structures – Arrays, hash maps, linked lists, trees, and graphs.
