Spectrum interview questions

Scheduled a phone interview, which was very successful. Then scheduled a face-to-face interview. The interview went OK, but she started asking me some technical questions that I hadn't studied for years. I couldn't answer a couple of them. Given some time to think, I could have, but I was not expecting those questions. Interviewer was abrasive. I already work for someone like that, and that's what I was trying to get away from. I really had no interest in working for them after the interview, but I never heard another word from them. If I go in for an interview, and I am not contacted afterward letting me know some sort of result, that's an automatic negative in my book. She also told me they conducted hair drug testing...nope.
