In the column of marriage, under normal circumstances, it is always unmarried or married. But some people either don't fill it out or keep their marriage secret. There are many reasons behind this situation: perhaps this person has been single, or his own conditions are relatively good and demanding, and he has not met the right person;

Maybe the other person is married, but he just doesn't want others to know that he is married; If it is divorced, it means that this person has a story and may experience some special things. When interviewing, you need to understand it tactfully. Of course, if it involves privacy, the other party doesn't want to say more, just say a few words casually and wait for the right opportunity in the future.

Your expected salary had better be kept secret.

The advantage of this writing is that there is a lot of room for manoeuvre when talking about salary merger with HR. Some people will directly say their expected salary for this job, or they will write a range. Usually, HR will compare whether the positions currently recruited are basically consistent with the expectations of the other party. If it exceeds a little, I can consider it as long as I can prove that I am really good.

However, if your expectations are very different from the company's salary standard. Maybe HR won't give you an interview, so keeping a secret is the best strategy. If HR communicates with you, you can say it in person, so you can attack and defend.
