It's more of a cheap gotcha than a valid test. If we take somebody like me, I learned to code in IDEA/PyCharm, these days mostly code with either Zed or OpenCode, and occasionally drop into nano and Positron. I wouldn't be able to do anything in Neovim without looking it up simply because I had no reason to learn it. A doctor who learned practices appropriate in the 20th century might now necessarily be hired for knowledge of these practices today.
