Can anyone please help me land a job at the united nations?

Answer 1

First go to the UN website (1st link) and look for the available categories. If you like a post fill the on-line CV and then just apply for the wanted posts. Some hints: Properly fill your CV (called PHP in the UN web), do not alter reality (do not lie), additional languages is a plus, previous experience is a big plus.
Other UN posts can be found on 2nd link.
Salaries nad benefits on 3rd link.

Answer 2
