I've started this challenge. So far only Caitlin Healy has been to work. Poor thing has got burned out with stress so I doubt she'll get promoted on her first day. Her hubby, Aidan, is still at home having a good time. He'll go to work soon.
One thing I read on the guide is that if you go directly to the employer of choice, you'd be able to start the very same day, but they only started on the next day.
