First, don't speak ill of the company.
In fact, we all know that a large part of the reason for leaving is because of the company. Maybe the salary is too low, maybe there is no development prospect, or maybe we met a great boss, .............................................................................................................................................., because such writing will leave a bad impression on the interviewer. Which company has no shortcomings? Right?
Second, I don't get along well with my colleagues.
Ditto. Even if you quit because you can't stand the intrigue in the office, please submit to humiliation. If you quit your job because of interpersonal relationship, and it's written in your resume, it's very likely that the interviewer will think you have a problem. If you say this in a panic during the interview, it will make the interviewer think you are weird.
3. Resign for personal reasons
This is the best way to write. You can say that it is due to some personal reasons such as marriage, illness, and further education. In short, it comes down to yourself, everything is your own reason, right, impeccable.
Say you want to develop further.
You can say this:
My current work situation is …, and I hope to work hard in the direction of …. In order to make up for this defect, I need to study further ... but I don't have time to study at present, so I choose to recharge my studies after leaving my job.
