Hello Paulo,
After I finished my training (2014), my activities were to create excel reports and make screens to list records, something simple.
When something more complicated appeared, I asked for help from a more experienced colleague.
But I believe that the ideal is for the team leader to assign tasks according to each person's experience.
Another important point is, don't wait too long to ask for help when needed, the community is here for that.
:D
Regards.
