Compared with the on-site departments, public holidays are days off.

If you are interviewing with the HR department, as long as the HR manager is still Xu xx, I recommend canceling the interview. Trying it casually will only waste your time. Don’t think you can easily outdo her—she is unlikely to retire anytime soon. The HR department is often completely wiped out and disliked by the on-site teams in various departments. I recommend not stepping into this trap lightly.
