I actually use Coleman for work. It feels so much nicer to type on vs qwerty. It reduces same finger movement (like e & d on qwerty) and enables common synergies, like ie/ei, ne/en, sr/rs, ar, st/ts, etc. It was also easy to switch to vs other layouts like Dvorak because it keeps important hotkeys where they should be, like ctrl+a/q/z/x/c/v so you don’t accidentally close a program while trying to select all.

I still use QWERTY often for my home PC because I play games and type at the same time and don’t want to change every hot key for every game.

What about those online 2 hour coding challenges to qualify for an interview? Those aren’t hard problems, but mainly to weed out the unqualified. However, I failed my first 3 coding challenges across 2 years before I got an interview. It’s such a BS metric to make all the test cases pass before even considering them. I knew once I got the actual interview, I would be golden due to my experience, but it was still hell getting there.
