Many have the idea that one can jump right out of animation school and into a top-level, high-paying position. While this can be true in rare cases, the reality is that you will probably start off in an entry-level position doing mintor, repetitive tasks that may or may not appeal to you.
But don't let that discourage you. Even if you wind up as an intern that spends eight to ten hours a day resizing texture maps, you'll be gaining the most valuable tool of your entire career: experience. SO its your hardwork and patience that counts too.
To talk about the best animation studios,here's the list:
Dataquest - Hyderabad
Crest communications - Mumbai
Paprikaas Animation Studio - Bangalore
visual Computing Labs (Tata Elxsi ) - Mumbai
Utv - Mumbai
Rhythm & Hues - Mumbai
Hope this helps.
