I should ask what the traits of senior people are—I've had some really nice conversations with interviewers by asking, "If you were in my position, what would you be doing?" Sometimes it seems like they just want me out of their hair after the rejection, which I understand.
Yeah, my bootcamp taught Angular and I taught myself React and built a couple apps with it. Haven't looked at Vue, I should do that. And no, haven't used RxJS—I'll look into that, thanks!
My technical answers have been solid so far. My "time when things were difficult" stories were a little clumsy out the gate—I'm coming from a field where I never, ever got asked questions like that—but I'm getting them together now.
I appreciate your words of advice and support! The advice to take a week off is especially good, and something I should probably put an effort toward. I've been in go-mode unremittingly since June of last year, and keep putting relaxation off because I don't want to miss an opportunity.
