Be as prepared for the dry questions as well as you can but the next interview, go in relaxed.
Be genuinely interested in the interviewer’s position with the company and slip in your own questions to he/she…
Any person, even a hard core, dry business only interviewer like’s himself as a topic of discussion and every human being appreciates the attention thrown back at them.
If they are that sour that they don’t, you may want to move on anyway.
In management most of my working life.
i never had a bad interview in my life because i went in relaxed, genuinely interested in a person as the interviewer that i may never see again in my life and wanted to know a little about THEM.
Had a highly successful life.
