My impression is that the hello messages developed into an unfortunate part of Google’s culture. I entered the industry in 2010 and didn’t run into this practice until 2015, when I began working closely with someone who was recently ex-Google (specifically, “you there?”/“yt?”). She was a super smart and kind person, and it was easy for me to coach her out of it, hence my thinking that she learned the bad habit at Google, and that it was in no way a manifestation of her personality (contrary to the suggestion of some comments in this thread that read more deeply into the behavior).
