Yahoo Inc. is planning its second round of layoffs in six weeks, while rival Google Inc. is preparing its biggest-ever year for hiring, underscoring the divergent paths of two of the Internet’s biggest names.

Yahoo said yesterday it will cut 1 percent of a global work force that stood at about 14,100 at the end of the third quarter, just weeks after announcing it would lay off about 4 percent, or roughly 600 people, from its work force.

In an official blog post yesterday, Google said that 2011 will set a record in terms of hiring — surpassing 2007, when it added more than 6,000 people to its roster, and last year, when it tacked on about 4,500.
