5th round interview with CFO-advice

Hi everyone! I’m a recent graduate searching for an entry level financial analyst position in FP&A. I’ve been interviewing with a company the past month and have made it to the 5th round with the CFO. I’m so drained from the process so I’m trying to keep my enthusiasm high. Does anyone have any advice on what I should ask/shouldn’t do? Any advice is appreciated!

it’s a virtual interview
