Just a sidenote regarding fulltime employment after 2 years contract; as I understand it, this happens if the base (non-scandi) has the right to live after 2 years of existence, but I have still not found what (or even who) decides whether or not to shut down. Anyone?
So, from what I see, the 6 month contracts are history, but there is still a lot of uncertainty regarding full-time employment offers after your contract is up.
