Long time lurker, first time poster.
I too am a 3rd round interviewee. I interviewed on Monday April 12th as early as possible in hopes to hear back soon after. (I too was told that Darden is going to "try" to nortify all 3rd round applicants before Darden Days.) The interview went well but I have yet to hear anything.
When I signed up there were only interview slots for April 12,13,19 & 20. I'm assuming they'd try to interview early in the week and review the applicants later. I'd be very surprised if they notified before all the interviews were over.
My bet/guess/hope is that we'll hear sometime on Thursday or Friday. Otherwise it would be very difficult to make Darden Days.
3rd rounders keep us posted! I'll be sure to post once I hear.
