You can write it down, it doesn't matter! If you change jobs frequently, you'd better choose a company that stays for a long time to write. Don't be too specific, but you should be prepared, because they will definitely ask questions during the interview, such as why you left your job.

If you change companies too much and stay for a short time, don't list them one by one, which will make you change jobs frequently.

Also, when choosing which company to write in, it is best to refer to the requirements of the position you are applying for now, and it is best that your previous work experience is useful now.
