It should be said that the key to your resume is what you said, not how the company you are applying for investigates it. Of course, this does not mean cheating. It refers to your interview skills and coping skills. You can say that you are an accountant. Do everything first and then consider the difficulty. If you leave, don't miss the opportunity!
3. Stop thinking about the cashier. Your goal is not to be a beginner. The junior professional title is already "assistant accountant". What you have to do is to be an accountant, and then be better qualified for accounting work. You are looking for an accounting job, not a cashier! Otherwise, it will be difficult for you to break through! Don't mention the original part-time job, just say full-time accountant. If you can answer all the questions raised by the interviewer (because you can understand and do it), then you will be confident.
To sum up: your biggest problem is "confidence". When interviewing for a financial job, self-confidence is the easiest thing to understand, because self-confidence represents your ability!
When you become an accountant, you will further study, take the intermediate exam and be further promoted.
About salary: don't care too much. Your excellent performance determines your salary level. If you show a lack of confidence and just want to be a cashier, your salary level will not rise.
If you are confident and get an accounting job, with your own efforts, I believe that a high salary is not far from you!
