The "Cisco Fatty" got busted for saying bad things about her potential employer.

In 2009, 22-year old Connor Riley was offered a job at Cisco when she sent out this innocent tweet that was meant to be sarcastic: “Cisco just offered me a job! Now I have to weigh the utility of a fatty paycheck against the daily commute to San Jose and hating the work."
Moments later, a Cisco employee named Tim Levad saw the tweet and replied, “Who is the hiring manager? I’m sure they would love to know that you will hate the work. We here at Cisco are versed in the Web.”
This exchange blew up on the internet, earning Riley the nickname, “Cisco Fatty.” To be clear, Riley didn't get fired. But she ended up not taking the job, explaining in a blog post that the tweet was actually made after she’d turned down the offer.
