Is it better to send a message to the interviewer or call him?

First, it depends on the relationship between you. Usually it is better to make a phone call and send a message of blessing. Because after all, during the Spring Festival, everyone is very busy. After all, I received a phone call from a close friend and a relative stranger in my busy schedule. How do you feel?

Second, because you have only a short contact, your understanding of him may not be able to talk about the topics he is interested in, and a simple telephone greeting may not be able to play any role.

Third, if you are good at writing, you might as well make a phone call. Generally speaking, it may be because he is your interviewer, so your words are a little nervous and have a negative impact.
