I've been introduced to this recently as I had not lived in bay area before. Apparently when one of BigCo's recruiters contact you saying they really like your experience and it would be a good fit for X, what they really mean is "Please jump in our interviewee grinder because we aren't getting enough volunteers." They just dump you into the usual pipeline without any discussion on salary range or an attempt at selling the company/role. I get hit up by multiple recruiters every week day; I don't have the time to entertain this bull or do full-day marathon interviews with zero sense of mutual interest. Luckily I only wasted an hour with one of the BigCo's before I caught on; if they get back to me I'll have to politely extricate myself because I will not be taking off time to go in for full day interview sessions.
