Scenario Based Interview Questions Link in bio!

@NayanUnfiltered awesome

@fromcodetocloud Focus on one. Complete one. OR Time bound the different tasks. Focus on each as per the time frame allotted.

Do you focus on one task or multitask?

Devops Engineers after implementing Auto deployment

@_jaydeepkarale clickbait

This is one of the biggest problem with thr current setup People upskill and the the educator/influencer community who earn from selling videos tells the world that its already dead In theory 70% of the industry probably hasnt even adopted it yet. The solution: Disconnect from social media as a learning guidanxe

@lakshyag404stc 🫡🫡

@fromcodetocloud Me right now 😭

@IamRameshSub yes bro😭

@fromcodetocloud Lol… deployments hardly go smoothly

@sharma1251 it automatically deploys to production ( depends )

@fromcodetocloud What is auto deployment?

@CommandQing i am imagining the situation on monday

@fromcodetocloud and then prod deploys at 11pm on a Friday because the pipeline doesn't understand work-life balance

This tutorial covers complete Kubernetes concepts. I have been following it for a while to learn the concepts I am not good at.

@kbkthebolt both r good

@fromcodetocloud Who is better in teaching for DevOps? Shubham or Abhishek??

@_jaydeepkarale yep its too long but worthy

@fromcodetocloud I learnt from this as well, I think I csn improve on this content, need to find time to record

@_jaydeepkarale Pro engineer is the one who fetches unique data without distinct💪

Two engineers wrote these queries: SELECT DISTINCT country FROM users; vs SELECT country FROM users GROUP BY country; Both return the same result. So why do both exist?

A StatefulSet in Kubernetes is used to manage stateful applications where each pod needs a fixed identity and storage. Key idea (simple) : Unlike Deployments (which treat pods as identical), StatefulSet gives each pod: - Stable name → app-0, app-1, app-2 - Persistent storage → each pod keeps its own data - Ordered start/stop → pods start and terminate in sequence Use StatefulSet when your app: - Needs data persistence (databases) - Needs unique identity per pod - Needs ordered scaling Examples Include: - MySQL cluster - MongoDB - Kafka - Redis (cluster mode)

@devops_nk i dont call back anyone. if they need it they will definitely comeback. they will interview other candidates and compare each of them and take decision

Interview scheduled day: HR called 4 times to confirm my availability. Interview went well. This week I tried calling HR 4-5 times for feedback no answer. Welcome to hiring in 2026, where there's only one-way conversation. 💔

Looks like Dislike button was already there, it was just kept hidden. He just enabled it in 60seconds.

@sauravstwt BOOK

DevOps interviews have changed. You’re no longer asked: “What is Kubernetes?” You’re asked: “A streaming platform serving 50M users suddenly starts buffering. Where do you start debugging?” If your answer is “check logs”… you’re not thinking deep enough. Real engineers think in layers: • Version changes • Environment scope • Resource pressure • Dependencies • Infrastructure health • Connectivity paths • Telemetry signals This framework is called VERDICT-7. Comment “BOOK” to get the DevOps interview blueprint.

If I were starting Kubernetes today, I’d learn this flow first. This is the actual path your application follows before it runs in a cluster. 1. Build the application Example: Java, Node.js, Python. 2. Containerize it with Docker docker build -t myapp:v1 . 3. Push the image to Docker Hub so Kubernetes can pull it docker push myapp:v1 4. Create Kubernetes manifests Usually you define: Deployment → manages pods Service → exposes the application 5. Deploy to the cluster kubectl apply -f deployment.yaml kubectl apply -f service.yaml Behind the scenes Kubernetes does this: Deployment → ReplicaSet → Pods → Containers start 6. Expose the application Using: - NodePort - LoadBalancer • Ingress Now the application becomes accessible. Understanding this flow makes Kubernetes much easier to reason about.

I Guess 70-80% of devops engineers haven't started their career as devops. They have actually switched from Support, Admin , Dev, QA etc roles Agree?
