Lady Ada tried to contribute something and make it a conversation instead of a monologue. That's exactly what I like about Dave's interviews. Naturally Limor and Horrowitz didn't exactly meet at eye level, but he has a few decades of top academic research on her and she has to manage a business. He interrupted her just as often.
I often cop the same flack for my interviews, because they aren't really interviews, they are just really a "conversation" and you go with the flow.
I for example often (without actually trying to do it deliberately) try to guide the conversation for the sake of either the audience, or my own personal curiosity. If I think of something interesting on the spot that they aren't mentioning or I don't get the sense they are going to get around to mentioning then I'll often interject.
Often it's a question I know the answer too, but I know the audience might not, and I know it will make for interesting detail. If so, you are damn right I'm going to interject.
Sometimes if you leave the question to later and do the "so lets go back to discuss this again..." it ruins the flow, or worse, you just let it slide by. That's worse than interjecting IMO.
Way too often I've seen bloggers interview people and they hardly say anything, and I scream at the screen "ask them more detail about what they just said" etc. It's very often boring because your average person being interviewed is not great at entertaining long story monologues. A good technical interviewer should be able to interject all the time with interesting questions as they come up in the conversation, whilst still ensuring they let the person ultimately finish what they were saying.
And it's not just technical, I see it in professional news and current affairs interviews too when the interviewee mentions something amazing or controversial, and the interviewer just goes on being "professional" and asks the next set question they have, and they miss the opportunity, that sucks.
I haven't watched the whole video yet, but I suspect Limor's style isn't too dissimilar to mine.
Everyone
thinks they can do better, but I'd bet they most will either be batshit boring, or do something not too dissimilar. No such thing as the perfect interview, and every interviewee is different, and you don't know what they are like until you are in the thick of it. I'd suggest cutting her some slack.
