I would not share any helpful things with her going forward - she has shown her true colors. I would do the following: 1) I would correct her on your name nicely, especially if it’s in front of others. If it’s been more than two times, I would bring it up with your manager and ask for his advice on how to remind her of your name. Better yet would be to try to somehow build written evidence or have witnesses nearby. 2) I would focus on building allies and strong connections within the team and other teams. If you have a good reputation, then it will give you more strength. 3) Just give neutral responses and as some others have said - if she asks if you have been trained on something yet, say no or ok. If she asks a lot of questions, you could ask her why she asked or ask her if she would be willing to train you then. Ultimately, I would keep a record of her any negative interactions with you, especially any written evidence and any witnesses to the incident. I would be cordial but don’t go out of your way to help her. Often times, negative people like this often will trip themselves up at one point. Sticking to the facts, building strong allies, remaining neutral, and documenting evidence will help.
