Google Tried to Patent My Work After a Job Interview

It’s down to individuals rather than culture in these things. By purely statistics, an organisation of any size has less than ethical people in it even if they have the best outward impression. Unfortunately these sorts of people tend to favour power and slowly work their way to positions that give them that. Then the whole org is a bad apple.

Having been in a similar situation before, the correct answer is “I’ll get my lawyer to contact you with our NDA process” or if you’re really worried “fuck off”.

It’s probably better to file patent first though. The patent is what you need to sell them.

Repeated unethical behavior is not the fault of a few bad actors, but of an organization designed to encourage that behavior. I wouldn't discount Google as being at fault seeing as how we already have two instances of Google's ATAP committing patent fraud despite little research and outreach being done.

One fun fact I stumbled across is any misconduct when filing for a patent voids the entire patent application, not just the claims that the misconduct occurred in: https://www.uspto.gov/web/offices/pac/mpep/s2016.html

Yes, failure to include an inventor of a single claim invalidates the patent family.
