Ask HN: Should I provide feedback on the recruiter

I just had a terrible interview experience with Google. To be clear the people interviewing me were professional but the recruiter wasted by time by giving me a lot of incorrect information on what to expect that consumed a lot of my time but also left me very poorly prepared for the actual interview

I am wondering if I should give this feedback when surveyed. I am concerned about pissing off a recruiter and getting blackballed for subsequent interviews both at Google and other jobs where this recruiter might eventually work

Any one know how the feedback flows and the possibility of being identified by the recruiter
