Pros
Socializing and brownnosing will move your career forward faster than any billable work you perform. If you enjoy mind-numbing and routine tasks, LTE may be perfect for you. They will hire people with zero experience, so recent college grads can get a start in the field. Most staff level employees are genuinely good, honest people; can't say the same for management. Many opportunities to work alone and avoid the office politics.
Cons
Extremely low wages with high expectations; profits go straight to the top while workers get scraps. Technical and engaging work is very sparse. Management will throw you under the bus very, very easily. Working overtime does you absolutely no good and is only rumored to impact bonuses. Equipment is poorly managed and maintained, which remains a daily progress inhibitor.
