The want ads.
Help-wanted ads are advertisements that businesses or organizations place to seek potential employees for job openings. These ads typically outline the job title, responsibilities, qualifications, and application instructions. They can be found in various formats, including newspapers, online job boards, and company websites. Help-wanted ads serve as a crucial tool for employers to attract suitable candidates for their workforce.
I believe post job ads are used by companies or persons wanting to fill job positions, often through third party websites. These postings advertise the position so more people will know about the opening.
