hello cohost. i have returned from my long absence to beg a boon of all of you tech people who also think the tech industry is awful

i'm applying for tech jobs in order to have money and am filling out a written interview (great format, legitimately, so many of these questions would have BSOD me in a video chat i'm grateful to have time to think over them) but my brain keeps telling me i don't know jack shit about what they're asking and i haven't learned anything in my ~five years of work and i'm hopeless and will never get a job

NOW...i understand a lot of that is my own brain bullshit and i'm working through it (with my therapist), but i was wondering if anyone could give me a reality check on a few of these concepts

1. i'm being asked a lot about web frameworks like react and vue.js and angular. am i right in my instinct that these are all essentially very very similar? i've done extensive work with polymer and some with angular and my brain just goes, yep, that's a component based framework. seems similar enough. Am i missing some incredibly important details about the differences between those systems? is this dunning-kruger at work? is it actually important to know the differences between these frameworks on a conceptual level?

2. similarly, is it reasonable that i do not really feel like i have the kind of knowledge about any of the languages/frameworks/tools i have used in the past to get into a similar conversation about them? i kind of feel silly just typing this out, like, of course i should have learned the ins and outs of all of them and what work and don't and what situation they're good for....but then another part of me is like. okay but i can learn to use any of them and web search exists, i can compare these in like ten minutes and make the decision of what i need to use.

i don't know how to ask for a reality check on "am i stupid about software" when i can't really explain what i know about software. it's just like, i've worked in it for years, i am genuinely good at working with teams and building stuff and figuring out problems and dealing with customers, but none of those skills can be "proven" on a job interview so like...i don't know how to hold out confidence enough to get through the process. sighs.

any general tips on how to sound smart in tech interviews welcome as well
