I previously interviewed for a position at a company through three rounds, each time meeting with the boss. They ended up not hiring anyone for the position.
A week later, the company posted a similar position in the same department - a restructured version of the job for which I had interviewed. I applied, figuring it was pretty low-stakes & that they wouldn't pick my resume again. For this job, however, I've again made it to the third round through HR (which doesn't seem to know I interviewed for the previous job), and I'm meeting with the boss again.
At this point, I'm exasperated. I've exhausted all the questions I've had, I've met with several members of the staff & visited the offices, I've researched this company, and I still really want this position. But I can't imagine she has any new questions for me that we haven't discussed the previous 4-5 hours we've met. How can I prepare this time around? What new things can I ask for an interview essentially five rounds in?
