Sheldor,Honestly? Maybe not time to panic, but time to start making sure that you have a solid back up plan in place. You will definitely get more, but its highly unlikely that you'll end up with >10 at this point I'd think. I know people personally who matched into Rad Onc with only a few interviews, so it definitely isn't over till its over. Also, theres a chance that perhaps the programs that will interview you just haven't sent out invites yet.
Whats your back up?
Thank you for being so helpful. Can you please tell me what a decent number of interviews at this time? I know that on nov 6 or seven should be the time when 50 % of programs have sent invites out.
Also what do you mean by a "good" back up plan?
