Some people always like to ask questions when they talk, just like auditing accounts. Is this a sign of low emotional intelligence?

It's not a sign of low emotional intelligence, just normal communication. When several people talk, there will be three situations. One is common. One or more talkative people say that they report what they have seen and heard. No matter whether others like it or not, they are not allowed to interrupt, and they rarely or never ask questions. Their words are generally irrelevant and verbose. The second is that several people are not very good at talking. To avoid embarrassment, some people have to ask questions. The third is to speak with a purpose, such as who you want to introduce to, of course, this is like asking questions like auditing accounts.
