How hard is it to get a job at the World Bank or IMF?

im a finance masters from the US and want to get into the public sector in development banking or projects. i realize that these 2 employers are the best for the kind of exp im looking for. however im also aware that they’re tough to get into, but just wondering how to start and what kind of competition i mite be facing. any info on how to get a foot in the door is appreciated, even an internship is fine at this pt. a chance is all i need…esp during these times.
