Summing up my experience: Now, first of all, you should be clear about your hobbies, and don't care too much about your major. I have also changed jobs here in Beijing, because I have no interest and have no motivation after a long time.

You can submit more resumes, but don't throw them indiscriminately, which will waste a lot of time and may miss important opportunities! Find a good target, just vote, and tell yourself that you will be admitted in every interview. Even if you are not accepted in the end, you should feel that the person in charge of recruitment in their company has no vision!

Always be confident!

If both companies really want you, do a survey first! Look at the company's prospects, your personal future development, welfare benefits, and the satisfaction of their employees. If the turnover of company personnel is particularly large, I suggest you give up!

Be careful, but don't waste time
