I recently had a screening call with an internal recruiter, and they kicked things off by asking me how I would deploy a web app on Kubernetes. While I found the question pretty straightforward, I'm curious how others would frame their answers during such interviews. What steps or details should I include to impress them?

When deploying a web app on Kubernetes, I'd start by packaging the app into a container image and storing it in a container registry. From there, I'd create a Kubernetes deployment resource to run that image in the cluster. After that, I'd set up additional resources like services to expose the app, ingress for traffic routing, and maybe configure persistent volumes depending on the app's needs.
When I get these types of questions, I sometimes suggest a feeler question for recruiters to gauge candidates' knowledge depth. If someone uses terms like 'XYZ,' I flag them because I find that super useful in narrowing down the right candidates.
Honestly, I'm not here to do your work for you. Just be prepared since there are plenty of tools that might dissect your answers later.
It's good to ask if the recruiter is looking for manual deployment methods or if they're expecting knowledge of tools like GitOps. It shows your depth of understanding and flexibility in different deployment strategies.
