ADT·Software Engineer·Technical Phone Screen
Jun 2026
Interviewed at ADT for what seemed like a cloud or infrastructure-adjacent role. One question on cross-region VM networking, not a lot of other context to go off.
- If a virtual machine in one region needs to communicate with a virtual machine in a different region, what does that process look like and what are the steps or barriers involved?
“Walked through VPC peering, routing tables, potential latency, and firewall rules.”
