What exactly is the clerk mentioned in the recruitment?

Generally, many people who do administrative work are called clerks. There is no technical content, but not everyone can do it well. Tea and coffee should be made, office supplies should be managed, canteens and vehicles should be managed, the company's annual inspection should be done, and everything should be done. Every company is different.

Generally, every department of a large company has clerks who are responsible for making documents, correspondence, meeting minutes, internal data management, etc.

Clerks are not demanding, but assistants and secretaries are demanding. Because an assistant needs professional knowledge and experience to assist his work.

Yes, every company is different. In some small companies, there are only a few people in the office, and a clerk basically does everything, such as cashier, administration, personnel, office chores, and the boss runs errands.
