Qualification timeline for Podiatry Externship/Residency

Hello everyone. I am new to SDN and thought I would see if anyone has good information about Residency requirements (i.e minimum GPA, class rank etc..) and if these requirements are due when we apply for Externships or when we apply for Residency? Do students get accepted at programs for Exterships before they qualify for that programs requirements for Residency? I am looking for more than simply opinion here. I couldn't find info on this online. Thanks for the help
