How many clients did you serve in your previous position?

The number of clients served in the previous position depends on the specifics of the work and the scale of the company. For example, as a DevOps engineer in a small company, you might have served dozens of clients or projects, whereas in a large organization, it could be hundreds or thousands.

It is important to note that in DevOps, it is often not so much about the number of clients, but about the number of services, infrastructure components, and teams for which stability, automation, and monitoring are provided.

Specifically, one could answer:

"In my previous role, I supported infrastructure and CI/CD for about 20 projects serving several thousand end users."
