If the previous job is very different from the job you want to apply for, and this work experience is likely to make the interviewer misjudge, thus affecting the success or failure of the new job, then you can not write, but you should think of an explanation in advance to deal with the doubts and doubts of the interviewer.
There is another situation that can't be included in your resume, that is, your work experience a long time ago, and this work experience has no direct help to the job you are applying for now.
Another is that short work experience can also be hidden in your resume, for example, you have worked in a company for 2 months. This situation, except that it may prove your instability, has no probative force in terms of ability and experience.
We say: we should seek truth from facts when applying for a job, and we can't make it up. The core is to show yourself correctly, and don't artificially raise yourself. The "inflated" job will expose ourselves. But I have no objection to beautifying myself on the basis of facts. In other words, it's best not to have plastic surgery, and it's ok to make "light makeup" appropriately.
From the richness of resumes, it is best not to have more than four different work experiences in a resume, just list the experiences that can prove their own characteristics; Too much will bring trouble to the interviewer's evaluation.
Maybe some HR friends will say, isn't this encouraging resume fraud? In fact, we all know whose resume is 100% complete. 100% Is it true? As long as the candidate is not making things up and artificially raising them, it is ok to trim his past. No one will put the details of peeking at the teacher's chest in class on his resume, although every boy has done so.
