If you feel "introverted and quiet", it doesn't matter. Not being fond of talking doesn't mean that you are not good at talking. As long as you can communicate with others at work and express your ideas clearly, there is no problem.
Of course, if you don't want to communicate with strangers at ordinary times, or find it difficult to express your thoughts directly, you will encounter difficulties no matter what position you are in.
In fact, if you are familiar with a job, you can naturally deal with it normally. Young man, be confident! !
