LinkedIn Sr. Software Engineer interview questions

Applied through website and got contacted by HR. Then set up a tech phone interview a week later. The phone interview was really really wired. Without any "Hi or how are you", he asked me 4 simple questions without online coding. Then he asked me "do you have any questions?" I asked him to give me a brief introduction about his team and what they do. Surprisingly, he answered: I do a lot of work. What you mean you do a lot of work??? and I asked 2 other question, he answered with no more than 5 words. And then it's over. I interviewed a lot of companies, no one interviewed like this. Make me feel rude, disrespect and unprofessional. I did not get responses yet, but i've already decided to reject this company.
