Juan Antonio Marin from INEGI wants to know if there is a way to delete and interviewer or supervisor account.
This action is called archiving in Survey Solutions and is described here:

Archiving does not make the particular account vanish without a trace, but hides an account from various selectors, e.g. for assignment or re-assignment. Yet any completed or approved interviews may still reference the archived account.
