46Phrog,
If you plan on applying for a non flying position that has a previous flying experience requirement don't hold your breath and definitely look for a stopgap if you need the money. The UN Job portal (called Inspira) is a minefield; you have to register on it, set up an online CV which is extremely comprehensive, then apply to be placed on the Consultant register (the majority of aviation related positions are classified as Consultant roles).
That process takes weeks. Then you can apply for positions after which you have to wait months. You don't get any reply if the position you applied for is filled from the register (ie internally), only if you have progressed to the next level.
Normally that would be an online examination of your generic aviation knowledge (types of cloud, explanation of relative humidity etc), and then you again wait weeks or months to see if you have passed. If not then no reply !
And so it goes on. I would advise anyone considering this to have more than one string to their bow.
