I echo meimg, I have red flags as well and I was able to land some IVs. Make sure you reach out to programs that you may have a connection with, for example any ties you may have to certain geographical locations would be a great place to start. If you know residents in certain programs, make sure you reach out to them also. As it is implied, be cordial when contacting these programs as they are getting slammed with 1000s of applications. Realistically, it's hard to reach out to all programs that you applied. However, it's worth giving it a shot and contacting programs with any sort of personal connection you may have with them. Hope this helps and continue to keep faith.
