What should I do?

It can be said that everything your parents are doing now is actually for your own good. Look at the pressure of the current employment situation. It is difficult to find a job that you are satisfied with. It doesn't matter where you are, no matter where you are in that unit, maybe your current unit is useless to your professional knowledge, but it is also a part of society after all. You may not learn skills here, but you can learn how to do things. Learn from others' experience and so on. If you want to do business, you have to deal with people. How much can professional skills play in such a society? Social experience is the key, so be prepared from now on.

What about you? Don't worry, I don't want to work in this unit now. Isn't it half a year before graduation? The job fair will continue. Maybe you can find the job you want there. There is also a saying that you can know what kind of job you really want before choosing a job, so that you can choose a job with a purpose. Good luck!
