Other headhunters wanted to ensure up front that Insider wasn't secretly recording them (we weren't), and only agreed to speak on the condition of anonymity — that what they said wouldn't be attributed to them or their company. Some would dish about the industry or their competitors, but discussing clients was verboten. Welcome to the secretive world of Wall Street quant recruiting.
