WSU is not competitive, but for some chapters recs are important. Our campus is moving to no frills, so it's becoming more laid back. First round is Panhellenic and is spread over two days (visit all chapters), second round is house tours and is 10 parties, third round is philanthropy and 6 parties, and preference is 3 parties.
Juniors do regularly get bids, but there are probably some chapters who don't take jrs (or so I've heard!). My pledge class had a junior.
Check out our greek site:
www.gogreek.wsu.edu its got a lot of good information on it.
WSU has 14 sororities, total (max number of members) is 90, and most of the chapters are around that 80-90 mark with a few going over 90 through formal.
Recruitment is the week before school starts (so we are back for work week right now).
