Also disillusioned with corporate tech and deleted my LinkedIn. I hate networking and my only network is my (actually quite) extensive and good college network.
I'm actually great at interviews generally though I've become less confident over time as I don't have many impressive achievements to brag about and the longer your career goes on and you've just "made websites and apps" every year the harder it is to defend increasingly senior positions.
Also feeling burnt out and I consider myself a generalist with no amazingly specific skills. Mostly js/ts, web dev, react. Basically the most common shit, I know it best, so nothing makes me stand out.
I don't have any advice, just wanted to share you're not alone in feeling these things.
