LA Retrofit interview questions

Very rude and unprofessional people and interview process. I was a new graduate from a TOP 25 university in LA area, I applied online for this company, one lady initially called me and left me a VM because I missed her first call to schedule an initial interview. I called back in 30 minutes as soon as I got her VM, another guy picked up the phone (guess he's the PM or higher management). I told him I was calling to schedule an interview. He was not prepared for my call and was looking for my resume. After a while he told me they don't hire new grad and wanted to ask me some very detailed construction technical questions, some of them I was not able to answer back to the time, and then he went rude and mad saying "you don't know anything about our industry then". I don't think this is the company I would ever work for or with and now I am working for an ENR 10 design-construction company, I am glad I did not join this company.
