Markus 'Notch' Persson has revealed that he turned down a job offer from Valve while he was working on Minecraft.
In a passage from the book Minecraft: The Unlikely Tale of Markus 'Notch' Persson and the Game that Changed Everything (republished by AllThingsD), Persson explains how he was invited to visit Valve as the beta version of Minecraft was beginning to grow in popularity.
After being shown around Valve's offices and meeting Gabe Newell, Persson was taken into a meeting room where a member of the studio's HR team had a chat with him.
According to the book, "[Persson] told him a little about himself and his plans for Minecraft before realising that he was in the middle of a job interview".
After answering some questions, Persson was told that Valve wanted him to work for the company, and he was asked if he was interested in becoming a Valve employee. Persson "answered politely but firmly, no".
Although Persson says the decision was one of the hardest he has had to make in his life, he also explains why he decided to reject Valve's offer.
"Somehow, I felt that Minecraft was maybe my chance to create a Valve, rather than work at Valve," he says.
