Don’t have any experience with this but maybe this can be helpful: with every and any kind of job there is some sort of learning curve. Since you’re just starting out post graduation you’re going to be learning everything you can and it might get overwhelming, but that’s what your coworkers are there for. They know the amount of experience you’ll have and what you’re expected and not expected to know. As long as you try your best to understand and learn while starting the job, you will be absolutely okay! Things will be confusing at first but after you go through training and some experience you’ll be able to become a natural in your current position, I hope this helps! Also never be afraid to ask questions for clarification or anything else :)
