Hours vary by region and seniority. It could be 8-5, 10-7, 1-9 or even a 10hr or a split shift, some time you can go home early, oftentimes you end up working later than planned, sometimes it goes as planned too. Really depends on your region and how busy/slow it is in that particular area. There really are a lot of variables, however most shifts are as mentioned in the beginning.
