XPO Line Haul Driver interview questions

I was messaged via email after applying for a local line haul position. From there an interview was set up. While there I incoward a few interesting situations. One, both the interviewer and I overheard an employee say "I should hang that guy up from his neck." Two, dumb interview questions, Three, failure to clearify why I wasn't offered a position. I got no reply from them as to why, even after asking for a reason. I'm an entry level driver with 3 months cdl experience. And 2 years non cdl flat bed work
