When you search for a candidate on TDB, you will be able to see the professionals' name, professional and academic profile, interests, and place of residence. In the same view, you can invite him/her to apply for one of your jobs by clicking on the 'Invite' button. Once you have selected the process to which you are inviting the professional, you will be able to customize the invitation message. When you send it, the professional will receive a notification on their Get on Board control panel, and in their e-mail.
Once the professionals accept the invitation to apply for your job on Get on Board, they will be able to contact you after sending their application. If they have not sent an application, and they are in the 'interested' phase (professionals who accepted the invitation but have not applied), they will be able to send you a message once you have started a conversation.
