International Biometric Software Developer interview questions

One of the company's recruiters reached out to me, and we scheduled a phone interview. He called me 45 minutes before the scheduled time, at 8:45. His explanation was something about how he likes to try to catch people off guard, so he can tell who's truly prepared. Despite the sheer disrespect for my time, I went ahead with the interview. It was fairly unremarkable. We talked about my background, the role, and the company. After that he sent a coding test off to me to solve.
