A recruiter on Twitter writes;

The work of a recruiter is not done once a hire is made. First week check in. Month 2. Month 3. Make sure you did your job which is to recruit the right people to the right organization. Don’t skip out on your duty. #recuiters

So be sure to take onboarding to the next level by following up. It’s good practice and makes the person you hired/placed feel valued.
