3Com, seeing its future in China, has promoted EVP Robert Mao to CEO and relocated him there. (3Com tried to sell itself to a Chinese investor group last year, but the Department of Defense blocked the sale.) To run its U.S. business, the telecom-equipment maker also rehired Ron Sege as chief operating officer. In 1999, then a senior vice president, he left the company to join Lycos, and subsequently served as CEO of Tropos Networks, a wireless-broadband startup. Nine years to go from SVP to COO? I've heard good tech jobs are hard to find on the East Coast, but this is ridiculous.
