It seems that you're definitely in the ballpark of who gets called for an interview, but the process is pretty opaque to the line pilots like us.

The good news is that we're expecting to hire a lot this year, so there will be a lot of slots to fill - good luck and keep updating your application with new flight times, etc, I would say at least once a month, twice a month would be better. May sound pedantic, but it shows interest in Delta.
