I understand. It's important that we aren't too patient, we should be proactive in looking for opportunities for learning and growth.
So my advice would be to communicate with your manager, schedule a one-on-one for 30 minutes. Tell them, that you would like to work on a challenging problem statement as you feel you're currently not getting to learn as much.
Also it's important to have this conversation with your Manager because their feedback would directly influence the decision of you converting to Full Time Employee or not.
So have this conversation with them as well, that if you get converted to FTE, how do they see your role and responsibilities change and how do they see your career grow here.
Since it is the initial phase of your career, have a discussion around your career goals and find alignment with the opportunities you can potentially get working here.
All the best. 1st job teaches a lot. We have all been there so don't worry, don't hesitate to reach out for any guidance or help here.
