Meng was Google employee number 107 and his job title was "Jolly Good Fellow".^[1] He joined Google in 2000 after working for five years at Kent Ridge Digital Laboratories in Singapore. At Google, he worked for eight years in engineering on projects such as mobile search and search quality. Tan earned his eccentric Google title after starting “mindfulness training” courses at the company — a groundbreaking mindfulness-based emotional intelligence course called Search Inside Yourself, which was featured on the front page of the Sunday Business section of The New York Times in April 2014.^[2] Search Inside Yourself is also the title of Meng's 2014 self-help book, which became a New York Times bestseller and was endorsed by President Jimmy Carter and the Dalai Lama.^[3][4]
