PowerVac Michigan interview questions

Was invitied for an in person interview. First, they HR lady didnt even tell me who I was interviewing with so I couldnt prepare ahead of who I was even talking to. I get into the room, they have two of their finance indivuals interview me, introduced themselves but didnt even mention what their roles were at the company. They asked me 1 question, legit 1 question between the two. Didn't even seem like an interview if you ask me and I explained in extreme detail my past work history as I was extremely qualified for the role. I asked them both about 6-7 questions that were very detailed about the role itself, what they are looking for skill set wise, and how I could bring my knowledge to help improve the business and they both looked like a deer in the headlights type scenario. Very odd vibe. The only thing the really stated is they wanted someone to take workload off the M&A manager, that was it. Extremely disappointed how they approached the entire interview process.
