Going through an interview process...

[PhiMuLady150]

Hi,

So I applied for a position earlier this week and they called me within 24 hours to have a "casual" conversation over the phone. She asked me to send her some references and that the other partner in the firm would call me to have the same "casual" conversation. The other conversation went well and he said she would call me soon to set up a formal face to face interview. Well, one of my references got a call from her yesterday and this reference told me that she has two concerns about me 1)That I won't be able to handle the high-stress environment and 2) That I am only 2 years out of college (even though I'm 25) (I took 5 years instead of 4 to graduate). I've had a pretty good instinctive feeling about things up to this point. I know this what we provide references to potential employers for but I'm just concerned. I know my references would support me and back me up but I just now have somewhat of a bad feeling. Any suggestions? Thanks.

ETA: The reference told me this information, I didn't ask her about the conversation because I know those are supposed to be confidential. I was actually a little offended that the refernce would actually reveal this much, I would of rather not known.
