The hotel invited me for an interview, but did not give a specific time.

I had the same situation as you when I applied for a job online. My practice is to call the recruiter to check the information first, and I will simply ask my basic requirements during the conversation. I will go to the interview at the appointed time after I think it is appropriate, which can effectively avoid the absence of relevant personnel when I go to the interview, because I don't know the company's situation, and it is not appropriate for me to waste time after the interview. The above is just my personal job hunting experience, for reference only. Thank you! !
