My wife has had phone interviews with two different companies in the same city that's far from where we live. One of the companies is flying her up for an in-person interview, and it's very possible the other company could do the same soon.
What is the etiquette should the interviews fall close to each other since they're in the same city? Say the first company had her return flight scheduled on the day the other company wanted her to fly in? Or if the second scheduled interview made flying back home and then back out a waste of time?
