It always amazes me how nearly every job posting somehow acts like Java is an acronym.
At my company I’ve asked that engineers proofread job descriptions so we don’t look stupid, but no, we still post for JAVA, NODE, and C SHARP.
I've always assumed that it is just because many of the companies asking for JAVA are still typing some of their job descriptions through mainframe terminals that haven't yet been able to afford upgrading to lower case letters and the job description work was a nice break between COBOL batches.
