Casium is an immigration assessment partner integrated with Ashby. Request a Casium immigration assessment on a candidate without leaving Ashby. Connect the two products once, add the assessment to an interview stage, and when the assessment is done, Casium marks it complete on the candidate's Ashby record with a link to book a consultation with Casium.
