Kristen O'Hara left Snap after just two months, thanks to what can only be described as a major bungle by Evan Spiegel.
O'Hara had been hired to a senior sales position, but was then reportedly offered the job of chief business officer. The company changed its mind just two days later, and handed the job to Jeremi Gorman, an Amazon executive.
O'Hara, unsurprisingly, quit.
