It was a multi-stage process. First a few conversations with a woman from HR, by email and then by phone. She was convinced I was a good fit, but wasn't sure about my technical skills. She then proceeded to ask me questions about concepts and structures that didn't exist in the language I was being interviewed for. She seemed to think that my lack of knowledge of non-existent primitives and structures was a flaw. Nonetheless, I was escalated to a proper interview with the technical lead. The tech lead was not much better. He asked a series of questions designed not to prove that I knew what I was doing, but rather that I'd made the same decisions in life that he had with regard to my education and experience. This interview was short and by the end of it, I think we were both happy I wasn't getting the job.
