Food Policy Fellow applicants have rated the interview process at CaliforniaVolunteers with 2 out of 5 (where 5 is the highest level of difficulty) and assessed their interview experience as 100% positive. To compare, the company-average is 100% positive. This is according to Glassdoor user ratings.
