When there is an existing candidate profile with the same email address, the system will give a warning that the candidate already exists. You can choose to merge the profiles so that you can maintain a single record with all related activities. This will be helpful when a candidate re-applies for a job or applies multiple jobs at the same time. You will be able to track everything in a single profile.
Click on Next to initiate the merge. Below windows will be shown.
Click on Proceed to start merging.
