Found out about position through word of mouth from former manager. Recommendations from current and former Cisco employees is key since cultural fit is very, very important for new hires. Basic competency - ability to do the job - can be discovered pretty quickly. What cannot, and what is very important at Cisco, is "Can I work with this person?" You don't get in the door if you don't already have impressive accomplishments, grades, or recommendations. That fulfills the baseline expectation for candidates. After that it comes down to cultural and team fit.
