I’m surprised they had this information so easily at hand. How did they even know that? They saw the tweet and the first thing that comes to mind is to query all the people they’ve interviewed?
On the other hand, if I, a random hypothetical engineer, were interviewing someone for a team, in a 1-1 situation, and they asked about what I worked I'm, I'm naturally going to be less guarded nor really prepared to sufficiently redact my answers.
