In the auditor's professional work experience, it is necessary to affix the company seal to ensure the authenticity and effectiveness of the work experience. Stamping is an authoritative way to confirm that the work experience provided is issued by the relevant company. When writing your work experience, you must include the company name, specific job responsibilities, start and end dates and other detailed information, and leave enough space at the end for the company to stamp. This practice helps to improve the credibility of resumes and is also a good professional ethics for job seekers.
