hi sis ianne16! same month tayo nag exam diba? i was also monitoring my online applications and the "under referral" also turned "regrets" without any interview whatsoever. but last week, HR emailed me for an interview. weird nga e. pero HR said, SOP lang yung interview, it's not yet for a particular department. they will still have to make a recommendation to a department in need of an operations assistant. and again, hindi rin sure, if ever daw ma invite, it will be a panel interview - 3 sila.
don't lose hope, it's still too early. september pa lang naman tayo nag exam! let's be positive

hi sis frozen toes, i actually applied for several posts but mostly op asst and started applying around july 2012. i think my application last august was the one they noticed because that's the application which changed to "under referral" status. then i took and passed the test last september. but unfortunately, no invites for an interview.
btw, the "under referral" status for that one post eventually turned to "regret". 
you're with adb na sis diba? how long did your application take?
