Are hotel executives trained by themselves or recruited from outside?

It depends. If there are suitable people inside, you can consider internal training. Of course, the first thing to consider is this person's quality and loyalty to the enterprise. The advantages are that insiders know the enterprise better, integrate quickly, the training cost is lower, it is relatively stable and not easy to lose. If you can't find the right person, you can consider external recruitment. Advantages: It can bring a good work experience to the company, and the company has a new atmosphere. If you are a graduate majoring in hotel management, you will have a better understanding of theoretical knowledge. Disadvantages: you lack understanding of the enterprise, it is not easy to join the company, and the cost of external recruitment is generally high. You will be asked to meet their standards during the interview. Whether you can adapt after work is unknown.
