I didn't check them out. But I don't think a company as big as ST hires only from 1 source especially with senior management. This is a taboo in talent management. Just sounds too incredulous. Diversity allows the organization to tap on the varied human resources so that they can harness the best from a wider pool of talents. I worked in a few MNCs in my whole working life and I have colleagues from a very wide pool of nationality and background globally. With competition worldwide, we have to stay ahead of competition so diversity definitely works in our favour.
