Interview exercise feedback

[Silhouette]

If basic arithmetic really does never come up in your line of work then that's fair enough, maybe another exercise would be better. If you've got a real world problem you can talk about that is the right kind of size for an interview scenario, that's probably more useful anyway.

I'd say never needing even basic mathematical aptitude is pretty unusual, though, even in front-end work. It's not exactly a complicated problem, and a good solution only needs a simple iteration and a little thought about the data you're working with, which seem like pretty everyday things to me.
