the company"s products are mainly for security. I have only just arrived at the company. Due to the lack of people here, I am now in charge of the company"s public service (technical level), which is a bit similar to the structure. I have no relevant experience in this respect. I would like to ask you, what does the public service department of the middle line of an Internet company do? the more detailed, the better. Four eyes see more than two. Thank you all!
