They contacted me via email to arrange a phone call. The initial email came from a do-not-reply email address with no contact information provided, so I had to call Rackspace to hunt down the recruiter who sent the email. I finally go to speak to the recruiter. She was very rude and told me my resume shouldn't have ANYTHING except software experience (I had also done some devops, sysad, and related work) and that I'd have to send them a new one. And she made it very clear that noone at Rackspace every reads cover letters even though their recruiting site asks for them. So I agreed to "fix" my resume and email it to her. She called a few days later and said the resume was good and she set up a phone interview for later in the week. She missed the phone interview. The next day she called to reschedule but never apologized for missing our appointment. She missed that appointment as well. This went on 2 more times and finally I got an email from her that they went with another candidate. In summary, the recruiter was rude, unprofessional, and inconsiderate. She played major games and then "went with another candidate" without even interviewing me!
