Pros
One thing Taco Bell has going for them, is their ability to hire people with really great personalities. Still, to this day, my favorite co-workers have been from my time at Taco Bell. They're just really great people, and I have nothing but love for them.
Cons
The position is essentially a glorified call center, like most help desk positions, and although it is a great stepping stone to get your IT career started, unfortunately most people end up staying there for 5+ years, making absolute peanuts. The work environment is also akin to a kindergarten. Management loves to micro-manage you to the bone, and expects you to come 10 minutes earlier than your actual paid and scheduled work time. The technical work is hardly technical. At the end of the day, Taco Bell sells tacos, and you really can't expect there to be a high, even medium level of technical challenges at this position. Working at the Help Desk is like, trying to get out of a 9-5 rat race inside another 9-5 rat race. If you're starting out in IT, this is a great opportunity only if you stay for 1 year. Learn as much as you can, and find greener pastures else where. I've done exactly this, and 4x my salary (and counting).
