Liberty Mutual Insurance Senior Software Developer interview questions

I had a 30 minute interview with the manager, talking about general comp sci experience. Then I moved onto a 1 hour coding interview. This coding interview had a typical Big O sorting question, and then went into a design section.

First round of phone interview with HR to discuss salary and job requirements. After 2 weeks scheduled video interview with Hiring manager to discuss team expectations after which he said there will be coding test with team members. No communications from HR after this. After I followed up with HR they sent me an interview invite for coding after 3 weeks. After the coding test with team (2.5hrs) NO response(pass/fail) from HR or hiring team regarding interview. Don't waste your time as I did. If the company doesn't care to inform on your interview performance(after spending 4-5hrs total) it's probably not a good place to work either.
