Antlers will only give you necklace that prove she owns you for the party.
If you want to go to the CEO's office at the party, you need one necklace that prove you're a manager. You need to buy one fancy necklace at the commercial center (so not a collar, not a choker) and go to the private room to switch them.
The character mastery skill, she will ask at the office or you can check the smart thingy in the employee portal in the morning and ask her to test your skill. In my experience she will not do it in the afternoon and not do it on a friday. Also you need to be at 18 to 20 for each skill to move or unlock the end of them.
I don't think you need to master all this to infiltrate Pawn office.
(But it will help to resolve the situation in act 5 to have max all your skill)
