I've found that this was true 5 years ago, but these days recent CS grads just don't know how to code like they used to. Many have never even toyed with web dev of any kind before, and lack many fundamental concepts outside of the traditional algorithms/data structures column of material. For example, I've found many junior devs with only a CS background don't understand client/server boundaries and often need to be taught how web browsers work on day one. Many have also only ever used Java and/or Python and seem to lack significant systems understanding that used to be commonplace in CS grads as well. I think one contributing factor to this is it has become increasingly easy to be a math major and easily get a CS degree by dipping into a few CS courses at a lot of schools.
