This is exactly what you are thinking now.May be You are bit confused about what are the things you are interested you dont have any idea because you haven't started learning anything...

But listen to me kid, this is really great that you are ready to adapt anything as you don't have any interest at all.I'll suggest you to go through the projects and see if you like those or not, if you like it then try to learn those topics you liked in the project and if you face any problem you can ask us we'll clear that mess up.

And there is a 'I am beginner' option if you don't have any idea at all but you want to learn we'll give you study material if you work well then you'll definitely get selected.
