Editing an existing topic or collection

I'm suggesting these edits to an existing topic or collection:

• [ ] Image (and my file is *.png, square, dimensions 288x288, size <= 75 kB)
• [ ] Content (and my changes are in index.md)

Please replace this line with an explanation of why you think these changes should be made.

Curating a new topic or collection

• [x] I've formatted my changes as a new folder directory, named for the topic or collection as it appears in the URL on GitHub (e.g. https://github.com/topics/[NAME] or https://github.com/collections/[NAME])
• [ ] My folder contains a *.png image (if applicable) and index.md
• [x] All required fields in my index.md conform to the Style Guide and API docs: https://github.com/github/explore/tree/main/docs

I propose the 'Interview' topic to provide a comprehensive resource for job seekers and hiring professionals on GitHub. This topic will cover strategies for preparing and succeeding in various types of interviews, enhancing candidates' abilities to present themselves effectively and navigate the hiring process confidently.
