The insight: The hotel I wanted to intern at at that time did not recruit the position of a receptionist, but I still boldly emailed the recruiter to introduce myself and explain the reason for wanting to do the internship with my CV. I think it's very simple, they see my sincerity, though they didn't need it at that time, after I applied, they've just had the demand, and so I was lucky enough to be the first candidate to apply early and thus have a better chance of passing. I realized I was competing with many others, so why don't I just go ahead, just do it because eventually at least we try our best, right?
