The Top 25 Metadata Interview Questions to Prepare For

Are you looking for Data Analyst roles at Meta? Heres a guide to help you out!

Metadata has become a crucial concept in the world of information technology. As data volumes explode metadata provides the context and roadmap needed to organize find, understand and properly use data. Whether it’s tagging files, mapping database schemas or enabling findability, metadata permeates virtually every corner of the tech landscape.

This makes it a hot topic for interviews, with metadata questions appearing frequently, especially for roles involving data management, architecture, analytics, and governance.

To help prepare, here are the top 25 metadata interview questions that could come up:

1. What is metadata and why is it important?

Metadata is “data about data”, providing context and extra information to describe other data elements and objects. It helps organize data, makes it easier to find, understand and work with. Metadata gives the bigger picture.

It’s crucial for

Findability – metadata like titles and tags makes it possible to locate data through searches

Data governance – metadata tracks the lineage of data, like modifications and access history.

2. What are some common examples of metadata?

Some metadata examples:

File properties – like file type, size, author for documents.
Column definitions in databases – naming columns, setting data types and constraints.
HTML meta tags – providing information like page descriptions and keywords.
IDs and tags used in databases, file systems and APIs for findability.
