If you're only able to see a candidate's initials and other information like their email address or phone number are obscured, this means that anonymized screening has been enabled in your Workable account.
Anonymized screening helps to reduce bias by redacting certain information about candidates. Obscured details will be visible later on in the hiring process as well as the ability to send emails and schedule events.
