I see 2 weak points, possibly 3: #1 "Resume screened by in-house recruiter", my experience is that they are not very well versed at "screening", they leave out individuals who are 97% qualifies, at the same time they screen in technically unqualified individuals who know how to play the "screening game". Get someone technical to do the screening. #2 "though salary isn't posted in the ad" if it's good, why not disclose it? #3 (Maybe) who does the 30m call? see #1 above.
