They’re probably in the wrong company. Are you suggesting there are isn’t an explosion of jobs and applications requiring advance math and machine learning or statistical inference? If so you are off the mark.
Doesn't invalidate your point, but the majority of jobs under the very broad 'data science' label just aren't super interesting after all. Guess you just have to be careful to examine exactly what a specific 'data science' position entails.
Any decent Comp. Sci. University will have enough math and statistics.
