Look yourself up. Peak, bracket, season and the title your character is wearing, straight off the ladder.
Drop in an email. That is the whole signup. No password, no forms, and your card is on the job board at your rating.
Sign in with Battle.net. Blizzard confirms the character is yours and the card turns Lime means the rank was read from the platform itself after you signed in there. Anybody can type a character name into this site, so a lookup never earns it and never will..
Then a hiring manager can check your rank instead of believing it. Here is a real one.
