Acting yourself is the best way to go about for an interview. They are not going to hire someone who is fake anywhere. As for looking for a job maybe work a part-time gig somewhere and still apply at hospitals until something comes up. Make sure you do fallow ups and such so they wont forget about you most places love that. But for sure never give up on what you learned to do before you even start it. Maybe you will have to move away from your area and apply to jobs else where.
