I recall pg previously stating that there was no correlation between how close to the cutoff an accepted candidate was and how well they ended up doing. Now Sam says the opposite. I can't find the original quote now and this was when PG was still in charge, so they probably have improved their interviewing process and collected more data since.

I can't answer that but pg talking about what may have been Sendgrid was quite interesting along those lines https://www.youtube.com/watch?v=YMqgiXLjvRs&feature=youtu.be...
