Are you familiar with ProTools and Dub Synchro (a software that facilitates ADR and dubbing). Have you done this kind of work before? (They stress that things at the Montreal Technicolor studio are different from other places you may have worked, but this is not true.) Learning curve of the job itself is short, but the dynamics of the place are chaotic because many of your potential future colleagues remain hanging onto jobs that 1. they are unqualified for (they consider, wrongly, time on the job to mean qualification), or 2. jobs that are obsolete (middle management has a hard time to figure out an effective workflow).
