More example catalogs need to be added where,

1. Catalog for internships, volunteering, gig workers / freelancers
2. Catalog containing jobs with required skills, rating, aging, educational reqs etc. Refer to examples like this.
3. Employer has a job application form hosted on their own career page that the BAP user is redirectd to after discovery
4. Employer has a job application form that can be natively rendered on the BAP's UI

Refer to as many career portals as possible and create different types of catalogs.
