Answer:
Situation was not handled properly.
Interviews would have been scheduled for different days
Step-by-step explanation:
Doubling bills is an un-ethical act of charging two different clients for the same time working while in reality the actual cost of time spent for each client is less than the bill submitted.This violates the law of professional conduct.
Alex's idea of submitting two different daily expenses to the two firms for interviews attended on the same day is double billing , which might attract fines or other punishments if discovered .
It would have been better if she scheduled the interviews on different days so far each of the firms are willing to cover the expenses.
