This was a lengthy and disappointing experience. It took a month to be contacted for this Talent Acquisition Volunteer position.
I was in contact with maybe 4 people and when I realized they didn't value my time, I declined moving forward.
The initial calls were to find out about my skills and confirm my interest in the role I applied for. After you've successfully passed that step, the supervisor or manager of your area of interest will contact you to inform you of your job responsibilities and required hours.
