Hello everyone,

I would like to understand how to best use the weight attribute related to skills in the section "Edit Job Profile". I would like to understand the impact of the use of the attribute of competence in other areas of the platform (for example Skills and Qualification). The range for the weight where it is set (the maximum figure that can be attributed)?

Thank you for your time
