Google rejected Instagram founder Kevin Systrom from its APM programme
Kevin Systrom worked in Google for 3 years before quitting and eventually co-founding Instagram which was acquired by Facebook for a billion dollars. In his book "How Google Works", Eric Schmidt writes about this incident. Salar Kamangar was very impressed with young Kevin who was a marketing associate and wanted to transfer him to the Elite APM program (Associate Product Manager). He was however rejected because the programme only accepted candidates with a computer science degree. Even though Kevin was a self-taught programmer and had a history of working with engineers he wasn't allowed into the programme. Read the book
