Can I apply directly to the hotel?

Generally speaking, it is not allowed, and sometimes it is considered very impolite; If you have a target hotel, then you should first search its recruitment information online and apply according to the process. If you rush ahead, you may not even get in the door. Of course, it is estimated that you can use this method in street shops, and regular large enterprises need to follow the process. If your resume fails, you won't be able to have an interview at all. Your direct intrusion is a contempt for corporate recruiters, so the result can be imagined.
