Just that really. I started a great new role a month or so ago. My boss is great. One of the girls on the team is clearly quite ambitious - nothing wrong with that - but she keeps asking me leading questions in front of my boss to trip me up, and always with a look on her face like she's Jeremy bloody paxman or something. It's hard to explain but for example - she's asked me several times since I've joined in a loud voice why I left my old job (i just wanted a new challenge) and the other day when my boss' boss asked me if I was settling in ok, before I even had a chance to reply she said - "don't worry! I'm getting all he gossip for you!" Which made me seriously annoyed. How can I shut her down? It's just her general demeanour around me screams - I don't like you. I'd just like to come in each day and not deal with her insecurities.
