I have heard not to bring a purse, but realistically I am traveling out of state to all of my interviews. For one interview I am driving with my mom and she will be dropping me off and picking me up after, I will need my phone to call her once the tour and such is over, and phones now are huge and it will look tacky in my pant pocket. I need my phone on me (turned off of course) and my keys and something to take notes on, I am planning to bring a professional briefcase looking bag. What are the thoughts on this? Is this really a no-no?
