Human Resources

I'm looking for someone to provide assistance with human resources, specifically with recruitment and hiring. I need help specifically with job posting and sourcing candidates, and need it to be completed immediately. Knowledge in the areas of interviewing and assessment as well as job offer and onboarding would be an added bonus. The selected Freelancer must have experience and knowledge with the recruitment and hiring process, including writing and posting job descriptions and sourcing new candidates. The ability to meet my strict timeline is of utmost importance.
