This advice won't help you right now, but when you do find your next role, try take an active role in tech interviewing. It's something I pushed hard to take part in two jobs ago, and it's shown me what good candidates and bad candidates look like, how to interview and how not to bomb the interview in the first few minutes. It's also helped me massively as a candidate.
I am registered as an interviewer at my workplace ($big tech company) and in the past 2 years I've been assigned just one interview. In the past year I've been assigned zero. Interviews are randomly assigned. Front-end web developer. Internally I can see they are hiring countless full-time PMs, PgMs, directors... but developers being hired are here on 6 month vendor contracts, and not full time employees, which is a change. Something is happening.
I was about to write the same. I volunteered in the company to help with hiring and after 20-30 interviews you get a lot of insight, what is looked at when evaluating and just in general being more natural when talking to people you see for the first time.
