California tech company people get really used to nothing being recorded because it's a Two Party consent state.

Good thing that shit doesn't fly when the other party is in a One Party consent state (or different country). Frankly two party consent to a call is some bullshit that only enables bad behavior on the part of the party with more power.

I've busted one big (Billions) tech company interviewer lying about my performance on a coding interview and was able to verify his lies by having a senior member of their staff (a good friend) compare my side of the notes with their internal documentation. The company recruiter was pissed and went off about how I wasn't experienced enough for the job even though I caught them lying. One of their other interviewers was my student at our university. I had years of experience on him, and all the other interviewers.

My advice is to always record and keep notes. Don't let them gaslight you. It might not be submissible in court, but fuck em, use a VPN if you have to.
