I have finally received the reply from Google. They say that they have considered my application carefully, but I am no fit for their team. Maybe not yet. Somehow this was pretty much the answer I was expecting. I can’t say that I am disappointed though. Obviously, I have to work on myself and try again at a later stage.
I have asked them if they have any guidelines for people who apply for the second time, or if they even have any minimum period between the applications, but I haven’t got the reply yet.
