HR Black List is a Chrome extension that provides an easy way to check the feedback about a person in LinkedIn from their previous employers. This tool is particularly useful for HR professionals who want to gather more information about potential candidates for a position.

By using HR Black List, users can view a person's working history based on their LinkedIn profile. The extension highlights if the person has any negative feedback from their previous employers. This feature allows HR professionals to quickly identify candidates who may not be suitable for a position due to negative feedback.

To use the extension, simply download it from the Google Chrome store. Then, while browsing LinkedIn, view a profile and the extension will highlight in red any candidate who has received negative feedback. If the HR Black List icon is red, users can click on it to read the feedback about the candidate on the HR Black List website.

HR Black List is a free extension developed by Alex Denisenko. It falls under the category of Browsers and the subcategory of Add-ons & Tools. Users are encouraged to rate the extension and provide feedback to help improve the product.
