Tech Companies Spend $4,339 (Or $21K In SF) To Recruit You & They Find You Here

does anyone know if these numbers are true for tech? I don't have any empirical evidence but 89 people seems high from my experience on both sides of the transaction. It seems to me that if that where the case it would be much more difficult to get a job in the industry. Meanwhile I generally have received an offer for good percentage of the job I have interviewed for. Off the top pf my head I would say it has to be somewhere near 70%. Now I am a good developer but that certainly can't account for that rate of hiring. Even of only 10% where as strong of candidates as me that would still be a 1 in 9 chance, which still would not account for a nearly 70% success rate. If it does then I think I should probably go into interview tutorials, but I tend to believe that it is not me but rather the market is more constrained than 89 applicants per tech job, if it is not then the H1B proponents arguments rings even more hollow.
