Many of the top manufacturers are non-American, and have a very "staid" corporate culture. The best are German or Japanese, so learning about those cultures is helpful.
In my case, I had done a lot of "extracurricular" learning and work, which was attractive to the people that interviewed me. Like I said in another post, on another thread, I have always enjoyed doing tech, and spend most of my free time, working on software.
I also come from a hardware background. My experience in connecting software to hardware was important. I should mention that most hardware companies treat software rather casually. I hope that's starting to change.
The job market, these days, is drastically different from what it was, but I suspect that these companies may be more "traditional" than a lot of tech companies.
