How about the management trainee in the catering department of a five-star hotel? Are there any development prospects?

You must first see if you have management potential. If you have the potential, you can work anywhere. There is a huge shortage of talent, not just in that hotel.

Basic management capabilities: being able to worry, having unity and cohesion, serving everyone, and coordination skills are the most important; and continuous improvement of professional knowledge, innovation capabilities, etc.
