Hi!
While I am not intimately familiar with the Auburn recruitment process, my best piece of advice on how to prepare for formal rush/recruitment this fall is to start securing reference letters, aka 'recs' as soon as possible!!
As mentioned by others, recruitment at Auburn is competitive and many other 'rushees' will have recs for most, if not all, sororities on campus. By searching GC, you'll be able to find info on how you can get recs, including contact info for those here on GC that are willing to write recommendations. While recommendations are not required, they can definitely help.
Best wishes this fall! I have heard many phenomenal things about Auburn Greek life & its 16 wonderful sororities
