How to draw the sound of knocking at the door

I heard more than one tutor tell the interviewee that you should knock twice when you enter the interview room. I don't know where this sentence comes from.

Since I started teaching social etiquette at 1992, I should know a little about the number of knocks. When tutoring candidates, I usually pass by here, and the requirements for candidates are not too high, because the core of the interview is not here, and the interviewer will not be too harsh on the candidates here. The most important thing for candidates is to learn better answers, which is the basis for getting high marks.

Specifically, when civil servants interview candidates to enter the examination room, they should bend their right index finger and knock on the door (except left-handed), and hold the rest of their fingers in their palms. Don't knock on the door with multiple fingers or even the back of their hands or palms. The sound will be noisy and ugly. The sound should be moderate, with an interval of 0.3-0.5 seconds, and knock three times. The tapping sound should be firm and not tense, with a certain intensity, but it gives people a sense of modesty.

Don't be too fast, it will give the examiner a light feeling; Don't be too slow, it gives the impression of laziness; Don't be too light, the examiner can't hear you, and when you hear it, you feel too timid, too nervous and too humble; Not too heavy. The examiner was frightened and thought that the robber could not accept the feeling of barbarism when he came to the door.

After knocking, wait 3-5 seconds. Candidates should push the door into the interview examination room whether they hear the examiner's password or not. Generally don't knock at the door again. Sometimes the examiner deliberately doesn't say, please come in and examine the candidate's reaction ability.

Knock at the door without interval. If you keep knocking at the door, the examiner may think you look like a law enforcement officer coming to check. Knocking on the door more than four times in a row gives people a feeling of boredom, less than three times, a bit arrogant and frivolous.

In fact, no matter in one's life or in the interview with the examiner in the examination room, you won't care too much or correct the way you knock on the door, but the good impression and bad impression you give people happen imperceptibly every day.

Of course, if the door of the examination room is opened or opened by the tour guide, you just need to smile and say thank you to the tour guide, enter the interview room, close the door and stand on the side of the examination table near the door, face the examiner's seat in the examination room, tidy up your posture and manners a little, and say hello to the examiner.
