Chargebee Technical Success Manager interview questions

Approached by recruiter first; had phone screen with them, then hiring manager 1 on 1, then operations director 1 on 1, and lastly an hour long demo with two others. It felt like there was a real disconnect between the demo instructions and what the panel was looking for. I was getting a lot of specific questions on things that weren't even mentioned in the instructions. Putting hours into that just to feel blindsided was kind of a bummer and trying to sound like an expert in a product you've literally never used until a few days prior shouldn't be the expectation. Good experience otherwise and I did like everyone for whatever that's worth.
