Call you in the middle of the night to inform you to go for an interview the next day.

Some companies will do this, depending on what position and position you are applying for. Ordinary employees don't need it, but if you are a reserve management employee, it is different. That's to test the adaptability and resilience of the backup employees. Sometimes even at two or three in the morning, the boss calls himself.

Many companies are familiar with personnel management and talent market, and resume exchange is nothing new.

Just don't bring valuables when I call you for an interview during the day or at night. If you only ask to fill in the form, it will involve filing fees, medical examination fees, etc., so don't pay.
