Anyone knows how many days they give to accept/decline offers after they make the calls?For late offers, I've heard 3 days.
How many days for early offers?
within a few days, whatever that means
"Offers
The IMF will consider each candidate’s performance in each component, as well as their overall rating, to determine which candidates will receive offers. In addition, other factors, such as diversity and particular skills sets needed by the institution, may also be considered.
Candidates who are offered a position in the EP typically need to respond within a few days. Offers are only binding for the current recruitment year and do not extend to the following year. Ratings and rankings are not shared with candidates."
