I've seen enough of their podcasts that I'm pretty sure Ethan is IEE and Hila is Si leading at least.

Ethan seems to care a lot about making good judgements about people's characters and such, getting as much information and hearing from all sides before judging people and even then he likes to hear what other people think. I don't think Ti valuers put that kind of effort into Fi. And his Fe isn't very serious and he mostly jokes about it and with it (so Fe demonstrative fits).

Hila might be SEI, but she doesn't seem very Fe; only shows it sparingly and when it's a part of Ethan's mocking jokes. Inclined to SLI. I think they might actually be a dual IEE-SLI couple. They seem to go well with each other, at least on camera anyway.
