How to Use This Interview Guide
If you’re new to Microsoft Entra ID, I recommend reading the five parts in order.
Part 1 → Part 2 → Part 3 → Part 4 → Part 5
This approach starts with the basic identity concepts and gradually moves toward tenants, domains, directory objects and subscriptions.
If you’re already familiar with Microsoft Entra ID and are preparing shortly before an interview, you can use the individual parts as a quick revision resource.
Microsoft Entra ID Interview Preparation
When preparing for an interview, don’t focus only on memorizing definitions.
Try to understand why each Microsoft Entra ID concept exists and how it is used in a real-world environment.
For example, instead of only memorizing the definition of a tenant, understand how a tenant represents an organization’s identity boundary and how users, groups, applications and other directory objects are associated with that tenant.
Similarly, understanding the difference between authentication and authorization, and between Microsoft Entra ID and Azure subscriptions, can help you answer practical interview questions more confidently.
