Liberty Mutual Insurance Assistant Director Advanced Analytics interview questions

I was contacted the next day after I applied and a phone screen was scheduled. However, on the day of the phone screen, nobody called. I tried to email the HR contact a couple of times after that and got no reply. It's okay if they would like to move forward to other candidates. But it's very unprofessional to just handle a scheduled phone screen like this. I don't think I would want to pursue any jobs with Liberty Mutual in the future.
