I have a 2nd interview scheduled for a TAC position in San Jose and was wondering if anyone might know what to expect. All I know is that it's in the intrusion detection/firewall group but unfortunately I don't have a security background. I do have my CCNA as of May 2007 but I'm not sure what type of questions will be asked. It's going to be quite technical but I don't even know where to begin studying. Any suggestions?
