Is the hotel's back adjustment strict?

Not strict. The hotel's callback is to do some basic checks through some contents mentioned in the interview, and ask the interviewer how his previous boss performed at work through the figures mentioned in the file, and whether the contents mentioned in the previous interview are true. Backtone, that is, background investigation, means that enterprises check and compare the personal background information submitted by the respondents through legal channels and methods, form a background investigation report, and assist the entrusted investigators to verify its authenticity.
