When you are taken to the screen which shows a job- press the A button, this will show you 5 jobs which are suitable for you, keep pressing A until you see one you like the look of. Then Press B to select it.
You will then be interviewed by 3 panel members who give you a 'x' or a 'o'. 2 or more 'x' mean you have to select another job as you are not qualified. 2 or more 'o' mean you are 'hired'.
Once you get a job you play the game by selecting the 'work' option from the connection icon and pressing 'B' when the away sign shows on the screen.
You can go to work and play the game as much as you wish.
You will be paid for your work the following day, the next time you select 'work'.
