That depends. Are the studios hiring? Is your work good enough/do they like it? How does it compare to the other reels they've recieved? Etc. When I finished school, I applied to 20 studios and heard back from 2, lol.
It varies from studio to studio. I touched more shots at Disney and Blue Sky than I did at R&H. My shots at R&H were always much longer than my Disney and Blue Sky shots though. They were all over 100 frames, whereas my longest shot (so far) at Blue Sky was about 60-70 frames. Shots are also moved along much faster at Disney and Blue Sky since the directors are in the studio and know how animation works. Whereas in vfx, you're working w/ live action directors who are more often than not off site and aren't familiar with the animation process. As the result, you end up going through a bunch of changes with your shots which causes them to take much longer to get approved.
So, the number of shots you get varies from studio to studio and even production to production. Your speed also plays a factor in this too. Obviously, you'll get more shots done if you're a fast animator. Lol, sadly I dont feel like I'm very fast so I don't have a ton of shots.
