Tells you something about their salt tolerance. It makes all the difference in plumbing together CRUD applications effectively.
My salt tolerance is so screwed that maybe I deserve to get failed in interviews for that... Still, seems quite unreasonable.
The salt thing can tell you that a person may be well-hydrated due to high sodium intake. Dumb test for "didn't tried it first".
What does it tell you?
I believe the intention is that it tells you they’ll make a modification without checking if it is necessary first. Some kind of impulsiveness.
Although, it seems pretty silly to me.
I think it is more like doing things from habit vs from first principles. Maybe they just learn how to do things once and then repeat them blindly. Not sure it’s a good test but I think that is the intent.
