Pros
I was attending night school for a degree in Computer Science and working construction 5 days a week. I knew nobody would want to hire a recent graduate who had absolutely 0 experience in the field. Cook Systems gave me that experience. i quit my construction job and put my trust in them. I went through a rigorous 8 week training program that really tested my abilities. In our training class, 16 people started, but only 4 of us completed it. That should give you some idea of how difficult and worth while the training is. After I completed the training, they used their resources and found me a job as a software developer with a reputable company. I've never been happier with my profession.

Now I have to attend a gym to keep my body from inflating due to a desk job
