Walk me through your Azure career.
I've been working on Azure for six years, three in Oman. Started in on-premises Windows infrastructure at an Indian managed services firm, transitioned to Azure as customers migrated, and for the past three years I've been Azure cloud application hosting engineer at an Omani enterprise. My remit: App Service, AKS, Application Gateway, identity integration with Azure AD, monitoring with App Insights, deployment via DevOps. AZ-104 and AZ-305 certified. Azure specialism with modern application focus.

Behavioural (STAR)
Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a major Azure project.
Last year I led the lift-and-shift migration of 30 legacy applications to Azure. Used App Service for web apps where compatible, AKS for containerised workloads, VMs for legacy that couldn't be modernised in this phase. Twelve months of work. Outcome: data centre footprint reduced, application availability improved through Azure's PaaS features, cost trajectory better than on-premises projected growth.
Cloud migration delivery.
Describe a cost optimisation effort.
Our Azure bill was growing faster than usage justified. I led the optimisation: right-sized App Service plans, switched non-production to scale-to-zero where possible, used Reserved Instances for predictable workloads, Azure Hybrid Benefit for Windows licensing. Cost reduced 28% with no service impact. Cloud cost optimisation is active discipline; default settings rarely match workload.
Cost discipline.
Tell me about a production incident.
App Service plan exhausted memory during peak load; auto-scale didn't trigger fast enough. Users affected for 20 minutes. Diagnosed via App Insights, manually scaled up to recover. Post-incident: tuned scale rules for faster response, added pre-emptive scaling for known peak periods, set up better alerting. PaaS doesn't eliminate operational discipline; it shifts what you operate.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through your Azure architecture approach.
Right service for the workload: App Service for managed PaaS, AKS for containers, Functions for event-driven, VMs only when PaaS doesn't fit. Network: hub-spoke topology, private endpoints for PaaS services where security demands. Identity: Azure AD integration throughout. Monitoring: Application Insights plus Log Analytics. Backup via Azure Backup. Security: Azure Defender, Sentinel for SIEM. Architecture serves workload requirements; over-engineering small apps wastes effort.
Azure architecture depth.
Describe your AKS operations.
Cluster sized per workload. Node pools separated by workload type. Helm for deployments. GitOps via FluxCD or Argo CD where pattern fits. Monitoring with Prometheus/Grafana plus Azure Monitor. Logs via Container Insights. Network policies for pod-level isolation. Pod identities for secure Azure resource access. Backup via Velero. AKS done well combines Kubernetes flexibility with Azure integration; done poorly is more complex than VM-based hosting.
AKS depth.
How do you handle Azure security?
Identity-centric: Azure AD as the foundation, conditional access policies, MFA mandatory. Resource-level: RBAC, least-privilege, just-in-time access for privileged operations. Network: private endpoints, NSGs, Azure Firewall, WAF on Application Gateway. Data: encryption at rest (customer-managed keys where required), encryption in transit. Monitoring: Azure Defender across resources, Sentinel for SIEM. Compliance with applicable standards. Cloud security needs deliberate configuration; defaults aren't enterprise-grade.

Situational
Hypothetical scenarios designed to test your judgement and approach.
An application team wants to use an Azure service that's new to the organisation. What do you do?
Engage early to understand the need. Evaluate the service: maturity, supportability, security posture, cost. If approved for use, develop standards: deployment patterns, security configuration, monitoring. Pilot deployment with the team. Support adoption. Standardisation matters for long-term operability; ad hoc service adoption creates support and security gaps.
New-service handling.

Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with application teams?
Application teams own their apps; my role supports their cloud deployment and operation. I provide platforms and guidance; they consume them. I respect their delivery pressure; rigid platform processes slow them down and create work-arounds. I'm direct on platform requirements (security, operability, cost); skipping them creates problems. The relationship is collaborative.
Service-oriented.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior Azure cloud engineer role at an Omani enterprise I'd target OMR 2,000 to 2,600 total package depending on cloud estate scale and on-call expectations. Azure specialism with major-migration experience commands a premium. I'd expect annual bonus and Microsoft certification budget. I'm on 60 days' notice. Beyond pay I'd value the cloud strategy maturity; cloud-native organisations offer different career experiences than cloud-skeptical ones.
Range and strategy preference.
