Same with me, never had any interviewer actually give me an actual real rebuttal, other than "but it scales!!".
I love software, but I really get tired of the blind cargo-cult culture of most of the industry.

* Version controlled deployments of your application via K8s state files * Once an application is live, you can easily deploy a new version and have traffic drained over for you * Recovery of applications (Pods) that fall over * Automatic replacement of your application when a piece of hardware fails (K8s will see the Pod has died and bring it back up elsewhere) * You can use labels and other mechanisms to "slice up" your infrastructure for specific work loads * The underlaying hardware can be virtually anything: a high-end physical server, an EC2 instance or a RaspberryPi -- you just define the resources available and what your application needs, that it's placed on the right hardware for you * With a few Pods setup, you can have all the hosts and Pods on the cluster report their CPU, memory, disk, network, and other metrics, straight into a Prometheus instance and have Grafana dashboards up nearly instantly, for free (in virtually in senses of the word) * New Pods are automatically added to the above setup, too * Integration with Cloud providers (so for example creating a service endpoint and saying you want it to be public results in K8s provisioning a public facing load balancer and IP for you and managing that...) * Much more..
This is all instantly available straight out of the box within 15 minutes with Kops on AWS.
I'm not arguing that K8s is automatically the correct answer, but to assume it's not an answer at all based on the feedback from interviews is a poor reason to dismiss it.
It does have a place and it doesn't have to be hard.
Hopefully I've been constructive here.
