I applied online. The process took 1 week. I interviewed at Rackspace Technology (Austin, TX) in Oct 2013
Interview
Recruiter quickly responded after my application in setting up an initial phone screener in which I was quizzed on things like commands, common ports, DNS, and then I was scheduled to complete an online TrueAbility test. After the test, I was given a phone interview and live break/fix, which I did not do as well on and was not selected for any further interviews.

Question 1
One difficult question was monitoring incoming pings.
The process took 4 days. I interviewed at Rackspace Technology (San Antonio, TX) in Jul 2010
Interview
Several phone interviews to weed out the obviously not qualified, followed by several interviews by others in the position you will be working at. These interviews are being conducted by your future co-workers. Don't try and BS your way through. They want to establish if you are a good fit for the company, if you have the technical skills, and your overall ability to be the kind of team member they want to work with.
They will probe to the ends of your knowledge and skill set. We all have a limit, they just want to know where yours ends. Not a big deal, really. Overall a very cordial yet tough set of interviews. Be yourself, be honest, and be happy.
