Is it discriminatory for institutions to require more than 2 years of work experience and pay social security continuously?

Because institutions can really set specific recruitment conditions according to the needs of recruitment positions, including requirements for certain work experience and continuous payment of social security. Recruitment discrimination means that an employer discriminates or judges a job seeker on the grounds of a person's characteristics or attributes in the recruitment process, which leads to the exclusion, unfair treatment or limited development opportunities of that person.

Recruitment discrimination exists in many different aspects, such as age, gender, race, nationality, sexual orientation, religious belief, marital status, health status and so on.
