Excuse me, does anyone know what the four-star hotel has, what work it does, and what requirements it has for entry?

Star hotels generally have rooms, lobby, catering, security, engineering, finance, human resources, general manager's office, marketing and other departments. The job content of each department is different, and the requirements for candidates are different. Generally, hotels above Grade 4 have certain requirements for employees' foreign language ability, especially in front office and catering positions.
