Microsoft Azure is a leading enterprise cloud, and its interviews test core services (compute, storage, identity, networking) and how you architect with them. Essential for cloud, DevOps, and enterprise roles. Here are the Azure interview questions that actually get asked, with answers. (See also our AWS and DevOps guides.)
Core services
- Azure Virtual Machines — compute basics.
- Azure Storage — Blob, Queue, Table, File; storage tiers.
- App Service and Azure Functions (serverless).
- Azure SQL vs Cosmos DB.
- Azure Kubernetes Service (AKS).
Identity & networking
- Azure Active Directory (Entra ID) — identity and access.
- Role-based access control (RBAC).
- Virtual networks (VNet), subnets, and network security groups.
- Resource groups and subscriptions — the management hierarchy.
Scaling & reliability
- Load balancer vs Application Gateway vs Traffic Manager.
- Availability sets vs availability zones.
- Auto-scaling; Azure Monitor.
- How do you design a highly available Azure architecture?
How to prepare
Azure rounds mix services with architecture scenarios. Practise explaining service choices and the identity model out loud. Greenroom runs spoken technical interviews that follow up on your reasoning. Pair it with our AWS and system design guides.
Frequently asked questions
What are the most common Azure interview questions?
Common Azure questions cover compute (Virtual Machines, App Service, Azure Functions, AKS), storage (Blob, Queue, Table, File and tiers), databases (Azure SQL vs Cosmos DB), identity (Azure Active Directory/Entra ID, RBAC), networking (VNets, subnets, network security groups), the resource group and subscription hierarchy, load balancing options, availability sets vs zones, and auto-scaling.
What is Azure Active Directory?
Azure Active Directory, now called Microsoft Entra ID, is Azure's cloud identity and access management service. It handles authentication and authorization for users, groups and applications, supports single sign-on, multi-factor authentication and conditional access, and integrates with role-based access control (RBAC) to grant least-privilege permissions across Azure resources.
What is the difference between an availability set and an availability zone?
An availability set protects VMs against hardware and maintenance failures within a single datacenter by spreading them across fault and update domains. Availability zones provide higher resilience by distributing VMs across physically separate datacenters within a region, protecting against an entire datacenter failure. Zones offer stronger high-availability guarantees than sets.
How should I prepare for an Azure interview?
Learn the core services across compute, storage, identity and networking, the resource group and subscription hierarchy, and the Entra ID/RBAC identity model, while focusing on architectural reasoning — choosing the right service and designing for high availability. Practise explaining service choices and HA designs out loud with a voice-based mock interview that follows up.
