Job Interview: Any tips, suggestions, moral support? All welcome!

Hello gents, I am a fellow camper for more than a year now.
I have not been too active on the “job hunt” front as I apply only to adds that requre my exact set of skills, so I am kind of “rusty” on the interview department and when the opportunity knocks its always a special occasion.

The job add reads as follows :
Infrastructure Admin
Server/Services monitoring
Services documentation
DevOps infrastructure developer
DB admin/maintainer

Debian GNU/Linux
gitlab & github
Apache, Nginx
Postfix, Dovecot

Any tips, suggestions? More than welcome
