I think this is more typical of positions being filled in Silicon Valley, where it appears that more programmers tend to have CS degrees. Or there are enough people with CS degrees that the rest of the community feels compelled to know and understand at least second year level CS theory (Big O and Data Structures).
I work in Texas, where this is not the case, and I've never been asked to implement a Linked List in any language. I have a CS degree from 10 years ago, and I can count on one hand the number of CS graduates that I've worked with in the past 6 years.
