Here is the US you'll probably start something where you work the weekends & slowly work your way up to a better shift was you gain seniority. Most shifts are roughly 4am-1pm, 10am-7pm, 3pm-12pm & 11pm-8am. Shop to shop they'll differ slightly depending on when the news casts are.
Also keep in mind that while you might have a schedule, don't think of it as a schedule. There were many occasions where I was 15min away from leaving for the day & I'm was asked to go shoot a fire two counties over, meaning I got home about 2 hours later than I was expecting.
The second place I worked at had 4 10hour shifts w/o a lunch break. (There is always time to eat in the car or edit bay, so you still eat, just never a "I'm on my break, can you bother someone else" break.) The plus side to this was that every weekend was a 3 day weekend.
When I started that job I thought I'd never leave due to the 3 day weekends.
Though after they cut overtime, health insurance went up & I was looking for a second job to make up for the lost cash, I realized that I no longer was going to have 3 day weekends & moved to a bigger city 70miles away w/ a nice raise.
