I'm moving to another state and am going to be interviewing for retail management jobs. My sister and I are going to take one trip to visit family (July 4th) and one to Florida to visit friends. Our friends want to get the plane tickets now for the beginning of August. Should I wait until I'm offered a job before telling them, or should I be up front about it? I'm afraid to buy tickets and then not be able to go because of work.
