Interesting empirical approach to hiring (I guess you have to do this in large organisations. Summary: always hire above the curve, if posible. I can also see the “no hiring manager” piece working, but wonder if the “fit” between manager and new hire doesn’t potentially suffer. I’ve always found that the last interviews in a series tend to be about fit and selling of the company, rather than the technical skills of the hire. Again, this is for more generalist consulting, not for specific technical competencies.
