A good rule of thumb as a founder and someone that's worked in big tech;
Big tech rules out any red flags. This means any engineers that get a passing grade across all interviews are in. Anyone that fails one of the multiple interviews is out, despite possible strengths.
Small tech should hire on the green flags. This means you can tradeoff weaknesses if they can do a job that needs to be done.
This is a specific application of a good general principle. Big companies need to watch for failure modes. Small ones need to watch for success modes, because the default is always failing.
