Hey I’m sorry, I’m not telling you you don’t know what you’re talking about. I do know what I’m talking about, it’s my field, I was just pointing out that often people mix quant and HFT which have different needs. Julia and KDB and Q tend to be more about statistical arbitrage or risk neutral pricing based model trading or whatever. They’re definitely widely used in funds, and a lot of traditional HFT have branches out from traditional HFT to include fast statarb and other things to juice margins and find a place for capital investment, so I wouldn’t be surprised if many of these shops use these tools somewhere but they’re not using Julia say in the kernel of the traditional HFT strategy.

I think if you feel like that’s happening to you the best strategy is to ignore it, but the second best is to prove your understanding. Explain with depth that can only be gotten from direct experience. If you know you know, either be confident in that or demonstrate it. I didn’t feel like you didn’t know what you were talking about though, I just thought you might be missing some nuance on the topic.
