Great potential - quite literally, the only obstacle to your own success is YOU. Startup mentality and very close-knit group, so the ability to balance having fun and keeping things loose yet delivering at a high level makes for interesting workweeks. If you are searching for a challenge and are more than willing to prove and not just talk, then this company is the right fit for you.

Ideal and successful personnel have the proper combination of adaptability and dogged determination - if you are a punch-the-clock type individual, you may struggle to make it over the hump.

Along with the high-intensity atmosphere and party vibe many here have described, it's all too easy to lose track of one's personal health and wellness. The ability to push back gracefully and to set the threshold for moderation (both in work and at play) is necessary for longevity.

Also, the nature of the industry requires constant training to not only maintain but excel -- it takes discipline and a strong hunger for learning to stay on top of the multiple new technologies and network security techniques that emerge on a daily basis.

Different training methods to keep methodology and chops fresh, yet relevant to a variety of learning styles. Granted the main focus is on revenue generation and product development, but keep in mind today's rookies are tomorrow's team leaders.
