Protools in the Film Scoring World
No matter what DAW you use to work in and produce, when working in the film scoring field you should have at least elementary knowledge of using Protools. Most recording studios run on that software providing nothing more but a Protools session file after the recording is done.
It is also very often your job to create the Protools session files before recording. This means to have the right tempo map and video files and potentially additional tracks all laid out properly in an empty session. It usually is a better way to create a separate session file for every cue as this is easier to handle on the systems and gives you better overview.
