I'm not sure why you're still talking about this. A basic "non-graphing" (90s "scientific calculator") is not capable of doing all the work for you. All it did was the basic things like add, mul, sub, sin, cos, etc. I am referring to one of these[1].
> It's not far from how common core, aka new math actually tries to teach it. It actually shows you understand the mechanics
I understand the mechanics of mathematics but still fared more poorly than I should have because I messed up a simple op like multiplication more often than I should have. My point is that had I had access to a basic calculator I would have scored significantly better in school. I went from Bs to As (80%, not sure what that is in GPA) in university by mere virtue of being able to use a simple calculator.
Again, not being able to use a [basic] calculator tests a signal that isn't actually important. Not being able to use Google/AI/whatever in your interview similarly tests an unimportant signal. The most important hire signal for a SDE is actually how they operate in a team and how they communicate with stakeholders, which these coding tests don't do.
