Five Rings Quant Researcher interview questions

Had a 1 hour HR call, then got invited for a 1 hour interview with 5 yoe quant researcher. The interviewer didn't bother using a proper headset and used the default webcam microphone, so was very difficult to understand. Also, I was quite surprised that none of the interview was about discussing my experience (I have 3 years of relevant experience in the field). They probably think that only asking brain teaser is relevant to find good quant researcher candidates.
