1. As a job seeker majoring in law, I can work as an administrative assistant or negotiate with foreign countries in this company. Because the company you want to interview belongs to an export company, most export trade involves dealing with relevant laws, so this kind of department is relatively suitable for you. In addition, this position can directly contact the top management of the company, which is helpful for promotion.
2. For the interview question, if you are asked what job you want to do in the company, you can answer it with "I wrote it all on my resume, and I want to work in XX", because if an interviewer doesn't even look at the resume of a job seeker, then he is incompetent. Specifically, don't panic. Before applying for a job, you should have a general understanding of the company you are applying for. You may not know the operation of the company, but the interviewer doesn't. What to do is what you have to ponder.
3. Generally, some shares of listed companies are reserved for employees, but no boss of listed companies likes employees who speculate in stocks during working hours.
4. On the issue of promotion, it is only a matter of time to get a good interpersonal relationship promotion as long as you have certain achievements in the company, but it should be explained that "soldiers who don't want to be generals are not good soldiers" but "soldiers who always want to be generals are not good soldiers". Therefore, it is very important to be practical and steady at work, and I hope to attract attention.
These are some suggestions for you, I hope they will help you.
