Sundar Pichai, the CEO of Google, was. interviewed for his position on April Fools' Day in 2004, it was just after Google introduced the email service. Although interviewers asked him questions about Gmail, he, like many others at the time, thought the service was one big prank for the company.
"I hadn’t had a chance to use it (access to Gmail was invite-only at the time), I thought it was an April fool’s joke," he told the 3,500 students attending a talk at his alma mater, the Indian Institute of Technology-Kharagpur (IIT-K).
