We don't necessarily hire people because of the degree or course they have done. The crew here are a varied bunch! All have different degrees, have done different courses (some none at all) and some have started at the bottom and learnt on the job.
Most of them however have demonstrated a level of skill, talent, passion, enthusiasm and tenacity, without having any specific qualifications. Although specific training in various practical areas can only help and further your knowledge, you should not get too hung up on whether you have a degree or not. The best way to learn is just to start.
