Although I am only a junior now and have no such experience, my primary school teacher is like this. After working for several years, he decided to take the postgraduate entrance examination and eventually became a master's student at Sichuan University.
People always say, "You should do what you want at your age". However, there is nothing so smooth under the sun! Some people think that they should go to college at the age of 20, but some people leave society early for family reasons and get married; Some people think that "standing at the age of 30" seems that 30 is the age when you should have a family, career and children, but some people are still climbing higher and higher on the road of learning.
Now you have a good chance to find a good job, but what if it conflicts with the postgraduate entrance examination? In fact, we have understood your idea from your question. You want to work first and then take the postgraduate entrance examination. But you are worried about whether you will not be admitted to graduate school if you work.
You put a hundred hearts here! You can still take the postgraduate entrance examination after graduating from college.
My primary school teacher is like this. He graduated from Xinjiang Normal University. Although it is a remote school, the employment is still very good. So he returned to his hometown, that is, the countryside, and taught in the primary school in Murakami. Later, when everyone outside thought that he would teach and educate people in this place all his life, he left to pursue his dream.
This is not to say that there is anything wrong with his behavior. On the contrary, I admire him. He has chosen to teach in this remote village for five or six years, but he still hasn't forgotten his dream. Abandoned the so-called "what to do at what age" shackles.
So, stick to your own path, ignore so many external factors, believe in yourself, go your own way, and don't look back.
