Liberty Mutual Insurance Financial Analyst interview questions

Interview was very weirdly paced. My first question from them is if I had any questions for them about the role, which lead to a very disjointed conversation. It was clear the one gentleman had no interview experience and was uncomfortable asking questions and providing answers. They did not give any pay range in the interview, stating they did not know. They also said they would let me know next steps in two weeks, which was very odd and a long time to me. They never ended up getting back to me about not getting the job, which I find extremely unprofessional.

First part of the Interview was conversation based with a few questions about the company, the second was a case study. Case study was very long and tough with 3 parts. They didn't give me a heads up that there would be a case study involved.
