Which gates will fire
Give this what a posting states as mandatory and what you can actually evidence, and it reports the gates where the answer is arithmetic — a number against a threshold, a place against a list. Everywhere else it says it cannot be determined, which is most places.
Everything stays in this page. Nothing you type is sent anywhere.
This says nothing about whether you would be good at the job, and it will not tell you how likely you are to be hired — there is no basis for that number and inventing one would be worse than leaving it out. It tells you which stated conditions your profile does not meet, so you can spend finite effort somewhere it can matter.
The employer side is whatever you type into it. The atlas holds no company records and this page does not create any.
