Understand the department you are interviewing with and their culture. Know what to offer.
Brown nose your way through the entire application process. Do not show any ambition or desire to advance, or eagerness for ongoing profressional development.
Showing any sign of ambition will be seen as a threat to the hiring manager's empire that they've spent many years building. You will probably be more qualified to do your prospective manager's role than they are, so they won't want to hire someone who can actually think for themselves and has recent relevant experience.
Play dumb, mention you like rugby lots, and pretend the university still delivers a "world famous student lifestyle" like it did in the 1980s and 1990s, even though today's reality is very different indeed, despite Marketing's attempt to continue the charade.
The best preparation would be to decline the interview because you have integrity.
