re wash u: it ranges. did you get the letter informing you that all everything is complete? some heard very quickly from them, but I only heard about my interview 3 weeks after getting that "everything is complete" letter (~ 6 weeks after being complete, i guess). btw there was someone from my school last year who interviewed in February (and she got accepted i believe). so they take their time...not necessarily a correlation between when they interview you and how competitive you are...it's all good...
don't know about stanford, but i'm sure plenty of others out here can help you out. 🙂
