Pros
The only pro that I can think of is that it is easy to get hired as a response technician.
Cons
I did not spend much time at onshore networks but I did get a chance to observe a few things. 1. Low pay for the tech industry. I was shocked to find out that techs that had been working there for over 3 years were not making more than what a McDonalds employee might get if the minimum wage was raised to what they have been talking about. 2.The manager of the team I was on routinely used profanity at not only people under him but to other managers and my coworkers said that he even used it towards executives above him in rank. 3. Absolutely no training. New employees are thrown out into the wild and have to fend for themselves. 4. Low morale at the company. People I talked to when my shift began and ended routinely talked about leaving the company and some of the discussions were very depressing.
