Add company friends, send resumes, and chat as follows. First check whether your friends circle and other content are open to HR, and check whether the content of friends circle is not suitable for each other. Then look at each other's circle of friends and find a topic to start from the beginning. If the other person's circle of friends is not open, then ask directly about the recruitment (during working hours is recommended). The most basic requirement is politeness. There is no mistake in starting a conversation with "Hello" and "Excuse me". You can ask about the interview time, interview content and so on. Then advanced requirements, according to the company culture, the position applied for, the information of the other party's circle of friends (age, hobbies, personality, etc. ) find a topic to bring the relationship closer. If you are about the same age/are fellow villagers/have common hobbies, you can relax and feel free. The highest state is to be able to "talk" naturally and kindly, and to know the real situation, salary and development space of the company by innuendo.
