It is difficult to provide an exact number without specific criteria for what constitutes "similar characteristics." However, job roles within the same industry, requiring similar qualifications and skills, and having comparable job responsibilities could be considered as having similar characteristics. In any given industry, there could be a range of job roles with similar characteristics, such as marketing manager, marketing coordinator, social media manager, and content creator in the field of marketing. It ultimately depends on the specific job market and industry in question.
