The interviewer is rude and blunt and arrogant, trying to poke holes in my resume. Some questions about the 5-stages CPU pipeline and memory barriers. In the job description, it says CPU/GPU/DSP engineering but when I ask the interviewers he said it's DSP only.

Technical questions around a table, similar to white boarding sessions. Several different interviewers. Questions about DFT. DTFT. Spectrum analysis. Modulation schemes. BW and period. The interview took all day. The feedback was pretty timely.
