The minimum requirement to get your profile approved is an 80% completion rate.
However, it’s important to understand your profile as a whole. Writing a one-liner to fill up a description box isn’t going to help you secure an awesome opportunity – but putting effort into explaining your interests, skills, and experience responsibilities, skills in detail will help employers to understand your level of competence better – and as a bonus you can say things you couldn’t add on to your CV!
After review, your profile will be approved and you’ll get a notification once it is.
