That's an awesome story!
I was lucky enough to do 4 month work experience in an animation studio when I was on a year break from college. I studied classical animation back then (2000). I got to spend time in every department of the studio, Storyboarding, Animation, Layout, FX and Admin. Amazing few months. Actually, that experience put me off wanting to pursue a career in an animation studio.
In college I had all these ideas for little short animations I wanted to do, but in the studio I realized I'd basically be working on a factory floor following someone else's creative ideas with no input, long hours and on low pay. One day I spent 4 hours in cleanup drawing 2 perfect ovals on 6 frames of animation paper. These 2 ovals were frames of glasses in a larger scene. That was my 'Nope' moment. I dropped out of animation college a few months after returning. With the progress of 3D over the last 20 years it's opened a creative avenue for me again.
Only recently doing some side gigs for a small studio I can tell the full time employees work long hours to very tight deadlines. I'm not sure what their pay would be like though. I think it depends on project to project. C4D in an animation studio I don't think is commonplace.
If I was pursuing a career in VFX then Houdini is the tool of choice without question. At least you are familiar with Redshift which also can be used with Houdini so that would give you a good lead into it. From what I've read of Houdini is the learning curve is steep but the payoff is great once you become familiar with it.
This short documentary about VFX studio that won an Oscar for Life of Pi was a an eye opener when I seen it
