Pros
Having worked for Frontier for a number of years, I can honestly say that it is the most fascinating company I have ever worked for. Having previously done my time in the daily grind of office working, it is now incredibly motivating to know that my time is going towards a genuinely inspiring vision.
In regards to the earlier review, I can see how someone might think that interns are heavily relied upon. However, the flip side of this is that interns are given meaningful responsibility right from the start, and many interns go on to work for Frontier or for other respected 3rd sector organisations as a result of their placement.
At Frontier you will work hard and be expected to take responsibilty, but in return you will work with a fun and inspiring team, towards objectives that actually mean something.
Cons
The main drawback is having to look at photos of the volunteers having great experiences in paradise locations, and wishing you were there!
