The interview process for me was very similar to other posts found on this site. 3 interviews, each increasingly more difficult, with the last one being in person. In talking with other recent hires, I feel it is important to note that all (especially in-person) interviews are different... and almost everyone left feeling that they did horrible and wouldn't get an offer. This is because one of the interviewers' main goal is to find out what you do not know... and how you react to not knowing this information. So, my advice is to be yourself and be honest about what you do and do not know. Even though the job is pertaining to network security... I was astonished to find out that I was one of the few people who came in with any firewall experience; Especially since over half my interview was related to firewalls. What they care most about is that you are passionate, want to learn / grow, and are someone that coworkers will enjoy working alongside and have great service skills for their customers. Another thing to mention is the entire process took a very long time, so don't get discouraged if you don't hear back from the recruiter long periods of time - they will usually contact you either way, and long durations between don't necessarily mean negative news. Also, If you are already in the San Antonio area, and are interested in getting Rackspace job, research Rackspace's Open Cloud Academy. It's a great (fairly inexpensive) program that offers learning / Certification training for Netsec as well as Linux and Windows. After graduating this program, A LOT of student's were chosen for positions. Chances are, if you get hired, you will be hired into the company's network security training program. This is basically a training program to get you ready for the floor. I saw it as a great opportunity to get some great training (for a few months) while getting paid.

Received message from Rackspace on LinkedIn in regards to an open position, exchanged e-mails with Rackspace. Sent my contact information to Rackspace as per their request. The interview was extremely technical, they throw the kitchen sink at you (metaphorically) to gauge your level of networking knowledge and how you react under pressure.
