Avantages
Volunteering in Tanzania was a once in a lifetime experience. Truly memorable. Well managed by London Head Office and locally by the Tanzania team in Morogoro.
Inconvénients
None that i can think of. It is volunteering, so don't expect a salary, but the rewards are all development; yourself, the community your working in and the venturer (youth volunteers) for whom you're responsible. The rating system on glassdoor isn't particularly relevant for volunteering, but will award a consistent five.
