I recently earned my CKA certification and have been studying Kubernetes seriously, but my current workplace uses Nomad and Consul instead. Our infrastructure is relatively small, and some of our workflows do not use containers, so Kubernetes has not been necessary.
I'm applying for platform and SRE roles that often ask for two or three years of production Kubernetes experience. I'm confident I can build and operate realistic Kubernetes environments independently, and I've completed a couple of substantial capstone projects. What I lack are real production stories involving incidents, migrations, outages, scaling problems, and similar operational challenges.
How quickly can experienced Kubernetes engineers tell when a candidate is exaggerating production experience? Is it ever reasonable to present personal projects as professional experience, or should I be completely transparent? I'm not trying to bluff my way through an entire job—I'm trying to understand whether a CKA, serious hands-on projects, and professional experience with Nomad and Consul are enough to compete for roles asking for production Kubernetes experience.

Even if exaggeration gets you through the interview, the job may immediately expose the gap. You could be expected to handle production incidents and design decisions at the level you claimed, while discovering that the certification covered only the starting point. Honest communication plus a strong portfolio is safer and gives the employer a realistic view of where you can contribute and where you’ll need to ramp up.
It’s better not to invent production stories. Experienced interviewers usually ask follow-up questions about trade-offs, failure modes, debugging steps, and what you personally did during an incident. Made-up experience tends to fall apart once they start drilling into the details. Be honest about using Nomad and Consul, then clearly describe the Kubernetes environments and projects you’ve built yourself.
Your background can still be competitive, especially for roles that value general platform engineering rather than a strict number of Kubernetes years. Nomad and Consul experience transfers well because you already understand scheduling, service discovery, deployment workflows, and operating infrastructure. Present your experience accurately and frame Kubernetes as hands-on project experience rather than production experience.
The certification is useful, but it mainly demonstrates foundational knowledge. Strengthen it with a realistic project: migrate a small Docker Compose application to Kubernetes and work through networking, secrets, persistent volumes, storage behavior, node affinity, upgrades, monitoring, backups, and failure recovery. Document the decisions and problems you encountered so you can discuss them confidently without claiming they happened at work.
