As you know, Flickr is one of the best-known brands on the internet with about 90 million users per month. They serve billions of pageviews and more than 7 billion API requests monthly for over 75 million registered photographers.
Many companies spend a lot of money on placing hundreds of ads for job vacancies in order to get the right candidate for a particular job.
Flickr, however, has found a way to cut down on ad costs and still ensure they get the right person for the job, saving their HR department from the daunting task of sifting through thousands of 'potentials.'
They advertise job openings for software engineers where only somebody worthy of the job will ever find it—inside the source code of the website!
If you find it, you will see it reads: "You're reading. We're hiring." That should cut down on a lot of paperwork and interviews.
Flickr is a part of Yahoo! And offers employees great benefits like multiple medical plans, breakfast, lunch and dinner, a smartphone, baby showers for new parents, and Yahoo! Gear for the kids. New parents also get a $500 daily habits allowance! When you start, you have 15 paid vacation days, plus 13 company holidays and—this may be the best of them all—unlimited sick days!
