The thing about 3d modeling and animation is that you should actually know a few tools. Most places ask you to have a portfolio with 3d projects. They almost never ask for specific applications. If you go to artstation.com and look at the tools modelers use they typically use a few at a time. Blender is insanely good for just modeling. you'll see lots of artist use blender just to model, then substance painter for materials then import into 3dsmax, cinema4d, or maya for the renderer.

A cool note I just learned recently is that game companies are using blender to make hard surface modeling easy. Like EA is using blender to make all the levels in the Deadspace remake and importing that into Frostbite(their game engine)

I'd say the most important thing is that you're a good 3D artist and have a strong portfolio. Smaller studios have a good chance of being software-agnostic in the 3D department, unlike big AAA ones.
