Thanks, esurio! Regarding my A/P prereq, no I haven't yet finished. My final exam is scheduled for mid-April. And I'm sure you will hear about an interview any day now. I know they assign interview dates randomly, so perhaps they send out the invites according to interview date and not surname? Also, they ask those invited to confirm if they will attend by Tuesday April 6, so perhaps they wait for cancellations before they send out the next batch (for scheduling reasons)? I really don't know, but I'm pretty certain they don't send out all the invites in one day so don't worry yet. Best of luck!
