"which they never read, at least nobody did at my interviews"

At small companies, the people that interview you are likely to participate in the hiring decision, so it stands to reason that they would read your CV. At companies like Google, interviewers are tasked with providing data that's not on your CV. Your CV would definitely be read by several people before an offer is extended.

"real professional interview involves a discussion about what the company does, what it current problems are (aka why are they hiring)"

For a company as large as Google, there is probably no one who could tell you what all the current problems are. Or even what all the open software engineering roles are about. And there's a lot of information on the web about Google, what they've done, what they're doing and trying to do.

(If I were being considered at a role at a small company, of course I'd expect the type of discussion you envisage, early on in the process. But at Google etc. I'd expect for those issues to be discussed with the recruiter (early in the process) and then with specific hiring managers (when they're ready to make an offer, but need to match you with a team)).
