HCM Recruiting: Candidate to Pending Worker Conversion

Summary

I've converted a candidate who has accepted my job offer in pending worker, but he hasn't received any email with his credentials. How can the system send it automatically?

Hi, 

I've converted a candidate who has accepted my job offer in pending worker, but he hasn't received any email with user name and password. When I create a pending worker this email is sent automatically. So, is it possible to send this email automatically also when I convert a candidate in a pending worker? How can I do? 

Thanks

Federica
