“If you can’t build a house with a hammer, you might then ask: how good are you
really at building?”
If I hired a carpenter and they showed up with a pair of pliers and nothing else, I wouldn’t let them start. Even if they were competent and motivated, I’d know they were going to get sucked into completely avoidable problems and they’d be way less time-efficient than a less competent peer who actually uses the appropriate tools.
If I were interviewing a software engineer and they didn’t use at least some programming editor (I don’t really care which: Sublime, Emacs, VS Code, PyCharm, anything), I’d assume they were either not very good at this or that they’re so idiosyncratic their coworkers would wish harm on them.
It’s not my job to tell a carpenter which hammer to use. But if they see a nail and reach for a spirit level, I’m sending them home.
