Will the company leader extend the probation period or dismiss you because you are introverted and don't talk much, but this person is serious and does a good job.

The boss won't fire you because you are introverted. It's that you don't do your job well, and you will be fired if you don't do it well. So you have to grasp a degree, that is, you have to realize that the company you are coming to is to work, not to say that people are divided into introverts and extroverts. So you have to grasp it. The most important thing is that you have the ability. If not, the company will not hire you.
