I feel like this is one of those moments that shouts “Hacker News is not typical”. A lot of people are employed through recruiters, including for Facebook, Google and the rest! Aiming to impress the CEO is all very well, but it’s not common.
At the start up I interned at during the beginning of my career, I got the interview and the job because I knew one of the developers. Every other job has been bog standard: apply , talk to recruiter, do phone screen, do onsite.
