▶ To get enough job seekers looking for a specific job in a specific location with a specific skillset with a specific number of years of experience (companies are very specific with what they're looking for) requires a large number of job seekers on your platform.

For example: ML recruiting for data scientists in the Bay Area with 3+ years of experience
