If it’s a job you genuinely want I’d suggest summoning some BDE - Big Dick Energy.

Go into the interview claiming it in your mind as yours. Visualise you in it. It’s your job if you want it.

To clarify BDE isn’t cocky arrogance - it’s just the subtle confidence of having a Big Dick - even if ya don’t have one!!

Ask them what they can offer you? Why would you want it, just as much as why they want you. This is a relationship after all.
