We would advise not to be really specific in your profile about a particular role or Employer. Keep your details relatively general but you write it in a way that would appeal to your Employer of choice.
We’d advise including things that they would be looking for such as details about your experience in their industry (if you have it) and if you don't then your interest in their industry and why it appeals to you. If there are certain interests, hobbies or personal traits that you think makes you particularly suited for a role with your preferred Employer, be sure to include this information in your "About" section.
You'll have the option to send a custom cover letter once you hit 'Apply',
