>>  I have given up entirely on interviewing for SV companies, and work 100% remote now.

Most of the people that I know that work remotely have preferred to work for SV companies, because they pay substantially more. What has your experience been?

If there was a better process, companies would adopt it, as it would give them a major competitive advantage. They're not complete fools.

Also applies to frameworks and languages?

Unfortunately, the companies that DO have a better process maybe have better retention and thus don't need to hire so much?

The same logic that states that bad candidates are always floating around applies to companies... companies that always have open positions are not necessarily the best ones, those seem to fill their open positions faster.
