In my experience and to my knowledge the querying process goes a little something like this:
At the query level, any of the following may happen:
A) No response means no
B) A form rejection
C) A request for a partial or a full (and perhaps a synopsis)
D) Perhaps a personalized note with the rejection (though this is incredibly rare)
With a request for a partial:
A) Form rejection
B) Personalized rejection
C) Personalized rejection with notes
D) Request for more pages (and maybe a synop)
E) Request for a full (and maybe a synop)
With a request for a full:
A) Form rejection
B) Personalized rejection
C) Personalized rejection with notes about what did or did not work for them
D) Personalized rejection with an R&R (re-write and re-submit and which could still result in a rejection afterwards)
E) An email asking to have a phone conversation which may or may not result in an offer of representation (at this point)
I think that's about it. Of course there are always exceptions to everything, but I think this is a general guideline of the process.
