Pros
Amkor is strong in emerging technologies. There is real support for new projects, both in terms in human and financial capital. The tools required to complete projects are readily available or are made available. There is good synergy between most of the US and off-shore technology centers. A strong effort by managment is made to increase knowledge-sharing. Amkor also makes a strong effort to accommodate work-life issues. Time off is given for personal issues w/ no detriment to career advancement. Flexible hours are supported as long as projects are completed on time. You manage your own time, however meeting project schedules need to be maintained.
Cons
US manufacturing is approaching neglible levels. Practically everything thing is done in Asia. This creates some trepidation among the US engineering staff. On occasion there is a lack of synergy between US and Asian staffs on problem-solving, though this seems to be improving. There tends to be late/early hours in order to hold conference calls w/ Asian factories due to international time differences.
