In includes several steps like the organization details the KSAOs (Knowledge, Skills, Abilities, and other criteria) required for the job; evaluation of a candidate over those criteria; and making an offer to the selected candidate.
Initial assessment methods stand for the starting ways through a candidate or an applicant is screened and shortlisted by the organization which includes ways like- application blanks, biographical information, and reference and background check.
