Opening & warm-up
How interviewers test your communication and preparation right from the start.
Walk me through your cloud infrastructure career.
I've been in infrastructure for seven years, three in Oman. Started in on-premises systems engineering, transitioned to cloud over time, and for the past two years I've been infrastructure cloud specialist at an Omani enterprise. My remit: cloud compute (VMs, containers, serverless), storage, identity, governance. Stack spans Azure primary plus some OCI and AWS exposure. AZ-104 plus working toward broader cloud certifications.
Cloud infrastructure scope.

Behavioural (STAR)
Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a cloud project you delivered.
Last year I led the cloud landing zone setup for our migration: organisational structure, identity foundation, hub network, shared services, governance baseline. Three months of work. Foundation enabled subsequent migration of dozens of workloads with consistent compliance. Landing zones done well save months of subsequent friction; done poorly create friction for years.
Foundation delivery.
Describe a cost issue you resolved.
Cloud spend exceeded budget by 30% in the first quarter post-migration. Investigated: over-provisioned resources, no scale-to-zero on dev environments, untagged resources making attribution impossible. Implemented: tagging policy enforced, dev environments auto-shutdown, right-sizing campaign. Spend back in budget within two quarters. Cloud cost management is engineering discipline.
Cost engineering.
Tell me about adopting a new service.
Business wanted to use Azure Container Apps for a new project; service was relatively new in our environment. I researched: maturity, peer experience, supportability. Engaged Microsoft on roadmap commitments. Pilot deployment with the team. Standards developed before broader adoption. Now used productively across multiple projects. New services need cautious adoption; jumping in without due diligence creates problems.
New-service judgement.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through your cloud governance.
Subscription/tenancy structure aligned with organisational and security boundaries. Tagging policy enforced via policy engine. RBAC with least-privilege. Privileged access through PAM. Logging consolidated for audit. Compliance policies as code, applied automatically. Cost management via budgets and alerts. Governance built in from foundation; retrofitting governance is harder than building it in.
Governance depth.
Describe your IaC approach.
Terraform for cross-cloud portability; Bicep for Azure-specific where Azure deeper-integration is needed. Modules for reusable patterns. State managed centrally with locking. CI/CD pipelines for applying changes. Drift detection on schedule. Code review on all changes. Modules versioned. IaC discipline scales infrastructure work; without it, clicking through portals doesn't scale.
IaC depth.
How do you handle backup and DR?
Backup per workload tier: tier-1 systems with point-in-time recovery, tier-2 with daily, tier-3 with weekly. Backup integrity tested regularly (untested backups aren't backups). DR pattern per workload: active-active for the most critical, active-passive cross-region for tier-1, regional with backup-restore for tier-2. RTO and RPO documented per workload. DR drills annually. Cloud doesn't eliminate BR/DR responsibility; it changes the mechanisms.
B&R/DR depth.
Category
Situational
Hypothetical scenarios designed to test your judgement and approach.
Multiple teams want different solutions for the same problem. What do you do?
Understand each team's underlying need. Often they're not actually different needs; they're different framings of similar problems. Drive convergence where appropriate: shared solutions are easier to support and govern. Allow divergence when needs are genuinely different. Standardisation has value; over-standardisation has costs. Judgement matters more than rules.
Architectural judgement.
Category
Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with workload teams?
Workload teams own their applications; my role provides the cloud foundation. Self-service where possible: standard patterns they can deploy. Engaged review for non-standard. I respect their delivery pressure; rigid processes create work-arounds. The relationship is enablement-oriented.
Service mindset.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior cloud infrastructure specialist role at an Omani enterprise I'd target OMR 1,800 to 2,400 total package depending on cloud estate scale and scope. Multi-cloud experience commands a premium. I'd value certification budget and training. I'm on 30-60 days' notice. Beyond pay I'd value the cloud strategy maturity.
