I did not mean to imply being an expert in all the languages listed, but having some knowledge of them and being able to write code.

I also think that an understanding of data structures is required to be able to identify the best way to deal with data in terms of processing and storage.

It is equally false to say none of what I mentioned is required. There is a broad spectrum between your statement and mine, and the truth is somewhere in between. The better prospect for a job is in the area of knowledge though I hope we can agree on that.
