MongoDB is a database that stores information in a flexible way. Unlike traditional databases that use tables, MongoDB uses collections of documents, making it easier to work with changing or unstructured data.

These MongoDB interview questions are designed for advanced or experienced MongoDB professionals possessing a good understanding of MongoDB.

These interview questions are also for those who need to demonstrate their ability to manage complex, large-scale deployments, optimize performance, and ensure high availability and security.

Good luck!
