Once I am completely done I will start my full time evening shift from 4pm - midnight. I didnt have to search anywhere. I didnt even graduate or finish my rotation before I had a job. So, my best bet of advice for you would be to ask around at the place you rotated. If they think you did a good job they will find something for you.
Most new techs get only per diem work or the graveyard shift.
New spots and shifts open up sooner than you think though. At the location where you rotated you have your foot in the door already though since you should know most of the supervisors there.
