System design interviews play a vital role in hiring software engineers and managers. These interviews test the ability of the candidate to solve problems under different constraints. A candidate’s performance in a system design interview is a significant factor in deciding the hire/no-hire decisions and the level assigned to the incoming candidate.

In this course, you’ll go through a miniature form of our primary course on system design: Grokking Modern System Design Interview for Engineers & Managers. This crash course aims to give you an overall gist of the system designing process using short, easy-to-digest problems. Each design problem of the course can be completed in about 15 minutes, giving you the flexibility to include them in your jam-packed schedules.

A **blob store** is a storage solution for unstructured data. We can store photos, audio, videos, binary executable codes, or other multimedia items in a blob store. Every type of data is stored as a **#key# blob:  A blob (binary large object) consists of a collection of binary data stored as a single unit. #key#**. It follows a flat data organization pattern where there are no hierarchies, that is, directories, subdirectories, and so on.

Mostly, it’s used by applications with a particular business requirement called **write once, read many (WORM)**, which states that data can only be written once and that no one can change it. These blobs can’t be deleted until a specified interval, and they also can’t be modified to protect critical data.
