Roku Senior Software Engineer - Infrastructure interview questions

I was contacted by a Roku recruiter via LinkedIn. He connected me to the Director of Engineering, Web Development in 2 days. While the recruiter was pretty nice and motivating, Director of Engineering was as cold as ice to me. I don't know why but he sounded like he had biases starting from the first minute of our call. He was late for 15 minutes for the phone call. He never gave me any feedback after I answer his questions. I'm sorry to tell this but he was like a robot. He wasn't even close to be 'nice'. I assume I was overqualified for the job. He was probably looking for just a front-end guy.
