Analog Devices interview questions

On-campus interview. Purely technical interview for 45 minutes - interviewer was not interested in prior work and did not know anything about the department (RF analog electronics) which I was interested in or the related field. Questions asked: Derive output and gain of simple amplifier (preferably without drawing small-signal model) Draw Bode-plots for RLC filter and more in the category of basic analog electronics Did fairly well at the interview and received the interviewer's business card but never heard from them again - no rejection, no nothing. Tried calling, emailing, calling HR, and absolutely no response. Got an automated email that they'll be back in office in 6 months. Weird.

This is an on-campus interview. The interviewer was nice and talktive. The main process was checking my resume and asking questions about it, not too much pressure. Basically like the conversation on career fair. At the last 15 minutes he asked me technical questions on Verilog, and was basic ones. The purpose of holding this interview was more like enlarge the influence of the company on campus and seems they don't really urge to hire people.
