My friend recently attended a Kubernetes-focused interview and got grilled for almost 20 minutes straight on K8s.

The JD was heavily tilted toward Kubernetes expertise and almost every question came from real troubleshooting scenarios.

Here are the questions he was asked 👇

1️⃣ Pod is running fine, all parameters look good, but traffic is not reaching the pod when users access the application.
What could be the possible reason?

2️⃣ What is ImagePullBackOff?
Why and when does it usually occur?

3️⃣ How do you debug inside a container?

4️⃣ If there are multiple pods, how do they identify and communicate with each other?

5️⃣ How do Helm charts work?

6️⃣ Do you actually use Helm for deployments in real projects?

7️⃣ Explain rolling updates in Kubernetes.

8️⃣ If a deployment fails, what are the next steps you perform?

9️⃣ How do you approach debugging a deployment failure?

🔟 If sensitive data needs to be passed in a deployment, how do you handle it?

1️⃣1️⃣ What are Kubernetes Secrets?
For what type of applications do we need them?

1️⃣2️⃣ Deployment is successful, but accessing the app returns 404. Why?

1️⃣3️⃣ What API errors have you faced?
What are 504 and 501?

1️⃣4️⃣ Explain what an API is.

1️⃣5️⃣ Difference between Authentication and Authorization?

Key takeaway:
Most questions were real-world troubleshooting based not theory.

If you're preparing for DevOps interviews (especially K8s-heavy roles), focus on:
- Networking
- Services & Ingress
- Debugging pods
- Rollbacks
- Secrets & ConfigMaps
- API fundamentals

Kubernetes interviews are no longer basic YAML questions.

They test how you think when production is broken.
Prepare accordingly.

@nalinrajput23 Why are you comparing IDE with AI tool?

[BEN OTTO David @benottodavid]

Started as a Network Engineer; now living in Cloud & DevOps.
It’s wild to think I went from configuring physical routers and switches to revolving around just 2 apps: VSCode and a Browser.
From hardware security to building APIs and Serverless—the toolset has changed.

Shell scripting is the one skill that separates DevOps engineers who panic during incidents from those who fix them in minutes.

I spent 8 years in Linux before I got into DevOps.

I wrote a minimalistic ebook on Linux shell scripting that will give you enough knowledge to start writing any shell scripts

I'm giving it away for free.

Follow me + retweet + comment "Living devops" and I'll send you the ebook in DM.

Participating in the Great Lock-In of 2025? Want to spend that time learning in-demand skills like RAG, Agents, MCP, and more?

At Microsoft, we’ve put together a free and open-source 9-part series covering the fundamentals of Python + AI, starting this October!

All you need is a basic knowledge of Python (you’ve got a month: 2 hours of daily study is plenty and there are so many free resources to learn Python) and a GitHub account.

Register to get access to all the links and resources. The series is available in both English and Spanish. 🙂
