Pros
You will be challenged at Telamon, which can be very rewarding. You may receive a great deal of cross-training and new product briefing. You will absolutely receive a crash-course (in a good way) in relevant technical disciplines if you are lacking in technical skills at all. They believe in training employees effectively and you will likely have plenty of time to learn if you are at all studious. A plus for some people might be that you don't have to think when you work at Telamon, your thinking is done for you. I say this as a middle manager in consideration of what front-line employees experience (the vast majority of new-hires).
Kontras
If you are a candidate for senior management or outside-plant work, it is doubtful any of the negatives of Telamon will apply to you; you're in the club! If you are applying for an entry-level position, expect you will not advance unless you are skilled in office politics and have a cut-throat attitude. I believe to qualify for senior management you must fire your best friend during a well-attended meeting. I have five jaw-dropping stories of disproportionate negative response to an employee's helpful or positive actions that fell in grey areas of policy; however, the only thing you really need to know is that if you do exactly as you are told--even if it hurts the customer and Telamon--you will probably be just fine.
