⚡Top 12 Terraform Interview Questions and Answers [2025] | Basic to Advanced

🎯 Why Terraform Interview Prep Matters

Terraform has become the default standard for Infrastructure as Code across AWS, Azure, GCP, and Kubernetes.

If you’re interviewing for a DevOps, Cloud, or SRE role in 2025 — chances are Terraform questions will come up.

Here’s the catch: most candidates only memorize commands, but interviewers test whether you can apply Terraform in real-world scenarios.

▶️ What You’ll Learn in This Video

In this interview-focused walkthrough, I break down the Top 12 Terraform Interview Questions and Answers into 3 levels:

📌 Basic Questions

• What is Terraform and how does it work?

• IaC explained → Why Terraform?

• Providers and Resources

• Terraform State file

📌 Intermediate Questions

• Plan vs Apply

• Drift detection (real-world example)

• Terraform Modules

• count vs for_each

📌 Advanced Questions

• Remote backends and state storage

• Concurrency and state locking

• Handling sensitive data

• Multi-environment best practices

🛠 Takeaway Example Question

❓ How does Terraform handle drift?

✅ Answer:
Drift happens when resources change outside Terraform. For example, if you delete a VM in Azure manually, Terraform’s state still thinks it exists.
When you run terraform plan, Terraform detects the difference and recreates the VM to match your code.

💡 This shows interviewers you understand Terraform’s real-world reliability, not just the commands.

💡 Why This Guide Stands Out

• Real-world focus → not just theory, but applied answers.

• Structured into Basic → Intermediate → Advanced so you’re never overwhelmed.

• Covers common traps interviewers ask, like state file deletion or switching from count to for_each.

This isn’t about memorizing — it’s about thinking like an engineer in an interview.
