What you can see is a quick summary of the shop but not the guidelines themselves. If there is a shop you think you would probably do but need to see the guidelines to be sure, you can contact the scheduler and ask if they can send you the guidelines because you aren't sure if you can do the shop or not. The scheduler contact is often included with the summary on the job board. Some schedulers will be responsive, some won't. Some jobs are easy enough to fill that they may not respond.
