Dear Basha,
For a trainee, I would recommend understanding all the processes and procedures of the organization. This will help you realize your own area of interest. After identifying your area of interest, you can ask your mentor to place you there so that you could pursue that.
Also, I would recommend that you try to learn things as if you are a student there and try to get along with the team so that you feel a sense of belonging. If the team feels the same about you, your chances of getting absorbed there increase.
Happy Learning and have a great career ahead!!
Regards,
Supriya
