What concepts should a person know who is applying for an SDE 2 role?

I am a software engineer and I am looking to apply for an SDE 2 role. I am not sure what concepts I need to know in order to be successful in the role.

When applying for an SDE 2 role, it is important to be familiar with basic concepts in software engineering, such as algorithms, data structures, and software design patterns. Additionally, it is helpful to know how to use common software development tools and platforms, such as GitHub and Jenkins. Familiarity with various programming languages is also important, as SDE 2 roles often require working with code in multiple languages. Finally, it is also beneficial to have some experience working with cloud-based services, as many companies are moving towards cloud-based solutions.
