Yeah, I mean the job was a research job where I’d be answering questions under time pressure, but I feel like there’s a difference between answering questions about an area of expertise, and answering questions about myself and my work history.
Also that introverts prefer to have questions in advance so they can reflect, and generally aren’t as good in the live situation - and as it was a library research job you’re going to get a lot of introverts :). (Sounds like you might be one too, and I agree, reflecting is a good quality in many cases)
