What's the difference between recruitment and employment conditions?

1. Generally speaking, employers need people, but they go to social undertakings to recruit talents.

2. Employment conditions are one of the recruitment scope. For example, there is a clerk vacancy in our company, and I want to set the employment conditions for this position (age 20, female, proficient in computers, etc.). If these conditions are not met, the general employer will eliminate the candidates and enter the interview scope if appropriate.
