First of all, personal information is necessary.
Now, sometimes it is no longer necessary to write personal information, such as height, place of origin, etc. On your resume. Many companies are reluctant to accept resumes without personal information.
Second, the final decision.
Remember, your resume should answer the following questions: Is it clear enough for employers to know your abilities as soon as possible? Have you written down your abilities clearly? Did you clearly write down the basis of your request for this job? Is there anything to delete?
Third, emphasize successful experience.
The employer wants your evidence to prove your strength. So certificates and personal deeds are essential.
