I interviewed twice with Secure-24, and were not that pleasing. They will always tell you "you did good, expect a call within two weeks." However, they never call. My last interview I answered most of the question correctly and they were pleased with me, but it seems that they are looking for the people who tolerate their childish environment with the so-called "nerf wars". I do not recommend secure-24 for those who are seeking a professional environment. They try to copy some of the huge companies cultures like Google, but they miserably fail. It is good to have certifications like Network +, A+, or security+ before applying to this job. They look for Comptia certification or maybe if you have a higher certification like the CCNA would be nice. The interview can take up to two hours depending on how much you and them talk to each other.
