Liberty Mutual Insurance Manager - Special Projects interview questions

I had a very bad experience with Liberty Mutual. I went through four rounds of interviews (HR phone screen, Hiring Manager phone screen, in-person interviews with three people, then final phone sign-off with the Head of the entire group), and the recruiter told me that I basically had the job and they were going to make me an offer. We negotiated salary and bonus and he said he'd get back to me shortly. Then he just disappeared. Completely ignored my phone calls and emails and left me hanging. I still have no idea what happened. I have a very negative impression of Liberty Mutual as a company that is disorganized in its interviews and doesn't treat candidates with respect, regardless of whether they plan to move forward or not.

The interview was more focused on financials and no technical questions were asked. There were three rounds of interviews, all of them went well. The last round was with HR, but it was pretty easy
