My crazy day in Post Production was usually 14 to 17 hours a day. That included watching one complete film at least twice a day or more. And being in the Zanic sound mixing theater, the sound design team would play and stop, play and stop, play and stop the film to add sound and effects here and there. The producer of the film was usually in the theater with us the entire time and he or she would direct the sound team on how they wanted certain effects how they wanted them.
Great money and a great place to work
Very long hours and big expectations. If you can't do the job, they will quickly find someone else who can.
