Seeing how someone drives an editor, IDE or cli is often a strong indicator of how good they are... Watching people arrow around in vim often gives me all the information I need when interviewing...
One of the top two or three developers I've ever known used arrows in vim.
Turns out that vim or any editor usage is only a (poor) signal and does not inform an observer on a candidate's product knowledge, arcane technical knowledge, past successful launches that a candidate has led, or helps glean any insight into the zounds of hard won battle scars in project design, system design, networking, concurrency, state management, etc.
Yeah how dare people use the keys specifically design to move around a text editor! Just use hjkl like they did on some machine decades ago because it had a limited keyboard.
