No.

[STRIKE]i[/STRIKE]If so, [STRIKE]H[/STRIKE]how and when [STRIKE]to [/STRIKE] do we use it in English, and [STRIKE]H[/STRIKE]how and when [STRIKE]to[/STRIKE]do we use"are you interested?"

We can never use do with interested, only with the verb interest.

Are you interested in grammar?
Does grammar interest you?

I am not interested in sport.

Is it a very common mistake?

A native speaker would never make that mistake from the age of about three or four.
Perhaps most of the "English" on the web these days is written by non-native users of the language. (When I do a search for this phrase, your question above comes up as number 2. Every piece of poor English written on this forum is subject to Google's searching. If I write "Interested do are you?" here (which I have), that phrase will probably eventually show up on Google. It proves nothing.


You cannot learn what is proper English by doing a web search unless you search for obviously native or official websites.
